  • DNA Structure "Two DNA strands intertwine to form a double helix. Each strand has a backbone composed of phosphates and sugars to which the bases are attached. The bases form the core of the double helix, while the sugar/phosphate backbones are on the outside. The two grooves between the backbones are called the major and minor groove based on their sizes. Most proteinDNA contacts are made in the major grove, because the minor groove is too narrow. The DNA backbone is assembled from repeating deoxyribose sugar units that are linked through phosphate groups. Each phosphate carries a negative charge, making the entire DNA backbone highly charged and polar. A cyclic base is attached to each sugar. The bases are planar and extend out perpendicular to the path of the backbone. Pyrimidine bases are composed of one ring and purine bases of two rings. Adjacent bases are aligned so that their planar rings stack on top of one another. Base stacking contributes significantly to the stability of the double helix. In a double helix, each base on one strand is paired to a base on the other strand that lies in the same plane. In these base pairing interactions, guanine always pairs with cytosine, and thymine with adenine. A GC pair is stabilized by three hydrogen bonds formed between amino and carbonyl groups that project from the bases. In contrast, an AT pair is stabilized by two hydrogen bonds. The specificity of base pairing—that is, C always pairing with G, and A always pairing with T—ensures ...

Nucleotides consist of a) sugar, b) nitrogenous base, and c) phosphate 2. Nucleosides consist of aa) sugar and b) nitrogenous base 3. The sugars of nucleosides and nucleotides are either ribose (found in ribonucleotides of RNA) or deoxyribose (found in deoxyribonucleotides of DNA). 4. The nitrogenous bases found in nucleotides include adenine (purine), guanine (purine), thymine (pyrimidine), cytosine (pyrimidine), and uracil (pyrimidine). 5. The bases adenine, guanine, and cytosine are found in both ribonucleotides and deoxyribonucleotides. Thymine is almost always found in deoxyribonucleotides. Uracil is found primarily in ribonucleotides and rarely in DNA, but does appear as a deoxyribonucleotide intermediate in thymidine metabolism. 6. Ribonucleotides are the building blocks of RNA and deoxyribonucleotides are the building blocks of DNA. 7. Nucleotides and nucleosides are made in cells by two general mechanisms - salvage pathways (use breakdown products of other nucleotides/nucleosides) or de novo pathways (synthesize nucleotides/nucleosides from scratch ...
  • Chargaff's Ratios Erwin Chargaff found that in DNA, the ratios of adenine (A) to thymine (T) and guanine (G) to cytosine (C) are equal. This parity is obvious in the final DNA structure. Originally created for DNA Interactive ( ). TRANSCRIPT The DNA molecule is made up of very long chains of the 4 bases: A, C, G and T. In 1950, Erwin Chargaff published a paper stating that in DNA of any given species, the ratio of adenine to thymine is equal, as is the ratio of cytosine to guanine. This is known as Chargaff's ratios and it was a crucial clue that helped solve the structure of DNA. Chargaff's ratios are universal: all forms of life obey this rule. Only the balance of AT pairs and CG pairs varies between species.

It's the polymerase (PAUL-IH-MUR-ACE), that forms the new bases, so that you have more genes in your cells, From the phosphate backbone, to the transfer RNA Very nifty, if I do say so. With the binding proteins, the strands won't anneal, And nothing can let them meet again The leading and lagging, strands are disjointed DNA REPLICATION! DNA REPLICATION! When the DNA is unzipped into two The lagging strand leaves okazaki* fragments To shake things up, and even things out Ligase comes around and attaches the two They come together to form a strand And DNA can replicate once again!

  • DNA 3D Structure Model with labels This is a quick and dirty model that I created in Maya. The deoxyribose nucleic seen here represents a basic interpretation of the chemical bonds that would be present in a single strand or double Helix. I colored the anti parallels both red and blue to simulate their adjacent qualities as they spiral upwards and string along and bond the genes themselves. The genes can be seen as Thymine and Adenine/ Cytosine and Guanine. These are the only formations these gene patterns can form therefore, Thymine will only bond with Adenine, and Cytosine will only bond with Guanine. Not appearing in this animation are the basic hydrogen bonds that connect the nucleotides. Also note that the genes coils themselves are elongated and therefore are NOT supercoiled.

  • NS 201 DNA Lab Adam Blomquist Philip Wong DNA, like that seen in the end of the video, is comprised of four different nitrogenous bases (adenine, thymine, guanine, and cytosine). Adenine is always paired with thymine and guanine with cytosine, this is called base pairing. The process by which DNA copies itself is called Replication and it takes place in the nuclelus (when the wheat germ was mixed with the detergent this is where the DNA strands come from). Transcription, the second step of information flow in which a part of a DNA molecule is transcribed to RNA. The final step occurs on the ribosome, where the RNA is "translated" into a strand of amino acids.

  • Methyl group drip, STAT! pseudoscience, or ***ized real science, someone, not sure it is Inmendham, is ***ing confused! Lets trip a few reality genes: We can identify, with the use of dye, the "turned off" genes. We can turn off a gene, in fact, simply by the addition of methyl groups to the DNA, at CpG sites (CpG sites are regions of DNA where a cytosine nucleotide occurs next to a guanine nucleotide in the linear sequence of bases along its length.), to convert cytosine to 5-methylcytosine. In the example on the video, coat color is a tag. The same process with an additional obesity tag has been produced in mice using environmental toxins: Interestingly BPA, the toxin recently reported in certain plastic baby and water bottles. The results were a lot scary! The change was passed on to the off spring. Normally brown mice born to a cloned mother with the obesity gene turned on and a yellow coat tag, were born with the yellow tag and obesity gene turned on. Pregnant and drinking bottled water? Your off spring may well have a stake in what is in that plastic. Once turned on, you can pass the awakened gene along. DNA and genes are NOT changed. I don't think it is evolution. We are talking about on off switches within the same unchanged DNA and genes. Will you have a tail and no limbs, or brown eyes and ten fingers as a human? The truth is you probably have the genes for either, it is more determined by the proper genes turned on telling your body you are supposed to be a human, not a bacteria ...

  • dna denaturation.MOV DNA denaturation, also called DNA melting, is the process by which double-stranded deoxyribonucleic acid unwinds and separates into single-stranded strands through the breaking of hydrogen bonding between the bases. Both terms are used to refer to the process as it occurs when a mixture is heated, although "denaturation" can also refer to the separation of DNA strands induced by chemicals like urea[citation needed] . The process of DNA denaturation can be used to ***yze some aspects of DNA. Because cytosine / guanine base-pairing is generally stronger than adenosine / thymine base-pairing, the amount of cytosine and guanine in a genome (called the "GC content") can be estimated by measuring the temperature at which the genomic DNA melts.[2] Higher temperatures are associated with high GC content. DNA denaturation can also be used to detect sequence differences between two different DNA sequences. DNA is heated and denatured into single-stranded state, and the mixture is cooled to allow strands to rehybridize. Hybrid molecules are formed between similar sequences and any differences between those sequences will result in a disruption of the base-pairing. On a genomic scale, the method has been used by researchers to estimate the genetic distance between two species, a process known as DNA-DNA hybridization.[3] In the context of a single isolated region of DNA, denaturing gradient gels and temperature gradient gels can be used to detect the presence of small mismatches ...

  • DNA Replication Song A song about DNA Replication, based on Backstreet Boys' "I Want It That Way." Lyrics originally written by these guys (adapted by Mr. Hsu). Online song performed by and Powerpoint slide show done by a simple high school science teacher named Mr. Hsu (live song performed by Mr. Moore and Mr. Hsu). mp3 available: c3 This song and video have been made solely for educational purposes. Its level of depth and detail into the process of DNA Replication are aimed at High School Biology students (at least the ones I teach). If you find any errors or omissions (ie I didn't mention Primase), this is due to the fact that I'm not teaching college-level Biology AND I'm being constrained by describing such a complex biochemical process through a fairly old pop song with incredibly repetitive lyrics. Mr. Moore and I actually performed this song as a duet for out students in class the day before spring break. If you're lucky, you might find a video of such a live performance somewhere in the vast internet (quite a few of them were recording me singing it in class, after all). This video is a result of me taking a simple digital camera and aiming it at my computer to try and record the performance my students experienced (so sorry for the crude recording and poor quality). I have recorded an mp3, and if I have time, I will find a place to upload it for public download, so that other Biology students can listen and study for their tests on DNA Replication ...
  • Part of DNA - Party in the USA Parody haha, you can learn all about Dna and miley cyrus songs with this video :) enjoy lyrics: Dna is found in a cell deep inside the nucleus welcome to the land of molecules where there's not a lot of roominess jump in the cell, replicating for the first time look to my right and i see mitosis real time this is all so crazy, everything is so ***y the helicase starts to work its way down the line thats when the dna starts to unzip and transcription starts to start and transcription starts to start and transcription starts to start chorus: and adenine hooked with thymine and cytosine with guanine they're copying themselves like yeah, making rna like yeah and in Rna the thymine switches with uracil it's all a part of dna it's all a part of dna the rna's out of the nuke all the organelles checking it out like where's an anticodon to make this all work out it's not hard to find a ribosome, that has a matcing anticodon they're in sets of 3, like a ponderosa tree they hook up a polypeptide chain emerges, that gets longer every time it goes off to become a protein and thats translation and thats translation and thats translation chorus: and adenine hooked with thymine and cytosine with guanine they're copying themselves like yeah, making rna like yeah and in Rna the thymine switches with uracil it's all a part of dna it's all a part of dna
  • OblaD OblaN OblaA Another BioSong, this time to the tune of Obladi Oblada.
  • DNA Replication Song Biology Project (Just in case you didn't know... We worked on this at like 4am in the morning... yes..yes... LAST MINUTE project!! but turned out really well!!) Background Instrumentals: Back Street Boys (I Want it That Way) Lyrics: Deox / y-ribo / nuclei / ic-acid / is made from two strands, a double helix So then, the strands come apart, Nitrogen bases, they start to unzip By DNA helicase H2 bonds Between adenine and thymine H2 bonds Between cytosine and guanine H2 bonds The ladder structure is strongest in Phosphodiester links DN / A Pol-ym / er-ase Builds the new strand From the / 5" to 3" Direction H2 bonds Between adenine and thymine H2 bonds Between cytosine and guanine H2 bonds The ladder structure is strongest in Phosphodiester links Now I can see that its replicating In a way thats quite interesting (YEAH!) No matter the distance, the leading strand Is followed by the lagging one Finally...the ligase Seals up all the breaks A new....a new....a new....DNNNNNNNNNNA! And it starts again!! Oh, how I love bi-olo-gy (yeah yeah yeah) It's better than chemistry And next time I have to go pee (I know) what's happening inside of me
