Why Does Rna Use Uracil Instead Of Thymine

Why Does Rna Use Uracil Instead Of Thymine. Dna uses thymine instead of uracil because thymine has greater resistance to photochemical mutation, making the genetic message more stable. Dna uses thymine instead of uracil because thymine has greater resistance to photochemical mutation, making the genetic message more stable.

Check out a sample q&a here. It is believed that thymine replaced uracil (the rna base) in dna because of the deleterious effects of slow spontaneous deamination of cytosine to uracil: Dna uses thymine instead of uracil because thymine has greater resistance to photochemical mutation, making the genetic message more stable.

Dna uses thymine instead of uracil because thymine has greater resistance to photochemical mutation, making the genetic message more stable. If it had thymine instead it would be mdna and not mrna. 9 what does cytosine consist of? Uracil is resistant to oxidation and is used in the rna that must exist outside of the nucleus.
