Why Thymine in Dna?

Explanation: DNA uses thymine instead of uracil because thymine has greater resistance to photochemical mutation, making the genetic message more stable. ... Outside of the nucleus, thymine is quickly destroyed. Uracil is resistant to oxidation and is used in the RNA that must exist outside of the nucleus.

Why is thymine only found in DNA?

Cytosine can deaminate to produce uracil. ... So using thymine instead makes it way easier and more stable, as any uracil inside DNA must come from a cytosine and so it can be replaced by a new cytosine.

What is the purpose of thymine?

In DNA, thymine (T) binds to adenine (A) via two hydrogen bonds, thereby stabilizing the nucleic acid structures. Thymine combined with deoxyribose creates the nucleoside deoxythymidine, which is synonymous with the term thymidine.
