The fourth base is Uracil.
Uracil is the base in RNA that pairs with adenine.
Thymine
RNA has Uracil (U) instead of Thyamine.
Thymine is a base found in DNA but not in RNA. In RNA, thymine is replaced by uracil.
RNA is single stranded and has Uracil instead of Thymine.DNA is double stranded and has Thymine, not Uracil.
RNA has the base uracil that DNA does not have.
RNA has the base uracil that DNA does not have.
RNA has the base uracil which replaces the thymine base of DNA.
Uracil is the base in RNA that pairs with adenine.
RNA has the base uracil which replaces the thymine base of DNA.
Adenines base pair in RNA is uracil.
Thymine is not present in RNA, only in DNA. The base pairs for RNA are adenine & uracil, and guanine & cytosine. Uracil replaces Thymine in RNA.
The nitrogen base uracil takes the place of thymine in RNA. So in RNA, uracil pairs with adenine.
An uracil base is in RNA but not in DNA
In RNA the base Uracil (U) replaces Thymine, this makes the bases for RNA A,C,G,U.
Thymine
RNA has Uracil (U) instead of Thyamine.
