Dictionary » C » Cytosine



(Science: biochemistry) A pyrimidine base found in dna and rna that pairs with guanine.

Glycosylated base is cytidine, it's derived from pyrimidine. It is one of the four nitrogenous bases, including in dna adenine, thymine, and guanine, and in rna adenine, uracil, and guanine.

... "the realm of biology" a week or two ago(self taught), and I learned just yesterday how DNA is made out of four nucleotides; adenine, cytosine, guanine and thymine... Yeah, that's how much I don't understand cancer and DNA. I was thinking about how radiation causes mutations in of ...

because it evolved so and today we can only guess why. Some of the proposals is the ability to distinguish cytosine's deamination product uracil as mistake.

Molecular gene (genome) concept scientifically untenable

... due to wear and tear of existence in the chromosomes only to be promptly replaced by insertases. A base can spontaneously undergo change. A cytosine, for example, will lose an amino group and become uracil. Uracil is perfectly at home in RNA but not in DNA. The enzymes called uracil glycosylases ...
