Dictionary » P » Pyrimidine Pyrimidinepyrimidine (Science: biochemistry) A family of 6-membered heterocyclic compounds occurring in nature in a wide variety of forms. They are planar and aromatic in character and include several nucleic acid constituents (cytosine, thymine, and uracil) and form the basic structure of the barbiturates. It is the parent compound of the pyrimidine bases of nucleic acid. ![]()

Results from our forumheyy if anyone can help... from the books, or simply search from the internet. there are 4 bases that builds the nucleic acid, comprises purine (adenine and guanine) and pyrimidine (thymine (in DNA)/uracil (in RNA), and cytosine). it's the gene expression. every cell that builds the body is differentiated and specialized ...

Re: PrimersThe "Y" usually means any pyrimidine. So each primer is probably a mixture of two. For the first primer the two possible end sequences would be GTT and GCT; for the second primer they would be GTC and GCC. I don't know if that makes ...

HIV Exposure to air... heard of it, it's hardly my fault. And can you tell me in which part of my post I said there would be thymidine dimers in HIV? Cytosine is a pyrimidine as well, and it can undergo dimerization as well as deamination under UV irradiation. I said UV light can cause "biochemical changes ...

HIV Exposure to air... that cause the inactivation of the virus (in air). For example, UV light causes biochemical changes in the microbe's nucleic acids, such as pyrimidine dimers that render the given nucleotide inactive. Also, mere drying is one mechanism - apparently when drying, the viral proteins get cross-linked ...

Miller experiment and it's contribution to origin of life... were done yielding more complex results such as: - all 20 amino acids, ATP, some sugars, lipids and even more complex compounds such as purine and pyrimidine bases of RNA and DNA I mean, how can you argue against all of these evidences?... life must have originated in this fashion... again, I am ...
