How many base chemicals are in a dna molecule
Web2 days ago · ASK AN EXPERT. Science Biology DNA is comprised of only 4 unique nitrogenous bases that code for all variation and all amino acids. If there were 6 unique nitrogenous bases instead of 4, how many would be the minimum number of bases required in each codon if there are only 20 amino acids? Explain how you reached that conclusion. WebEach nucleotide in DNA contains one of four possible nitrogenous bases: adenine (A), guanine (G) cytosine (C), and thymine (T). Adenine and guanine are purines, meaning that their structures contain two fused carbon-nitrogen rings. Cytosine and thymine, in contrast, are pyrimidines and have a single carbon-nitrogen ring.

Spontoni, P.; Gaiassi, A. From Renewable to Fine Chemicals Through Selective ... WebDuring DNA replication, uracil will pair with adenine rather than guanine (as it would if the base was still cytosine), so an uncorrected cytosine-to-uracil change can lead to a mutation ^5 5. To prevent such mutations, a glycosylase from the base excision repair pathway …
WebThe nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA. The ribose sugar of RNA is a cyclical structure consisting of five carbons and one oxygen. The presence of a chemically reactive hydroxyl (−OH) group attached to the second carbon group in the ribose sugar molecule makes RNA prone to hydrolysis.
