Thymine in DNA
Uracil in RNA
Uracil is the base in RNA that pairs with adenine.
In DNA the base pairs are Adenine with Thymine and Guanine with Cytosine. In RNA Thymine is replaced by Uracil so the base pairs are Adenine with Uracil and Guanine with Cytosine.
The phosphate base that pairs with Adenine in RNA is Uracil. In a DNA strand Adenine would pair with Thymine.
adenine
In DNA: Adenine base pairs with Thyamine A=T In RNA: Adenine base pairs with Uracil A=U
Uracil is the nitrogen base found in RNA that pairs with adenine in DNA.
Thymine base pairs with adenine in DNA, forming a T-A base pair. Uracil base pairs with adenine in RNA, forming a U-A base pair.
Adenine is the purine base that pairs up with thymine in DNA and with uracil in RNA.
In RNA, adenine binds to Uracil. In DNA it binds to thymine.
In DNA adenine pairs with thymine. In RNA adenine pairs with uracil.
A purine will always pair with a pyrimidine. Examples of purines are adenine (pairs with thymine or uracil) and guanine (pairs with cytosine). Examples of pyrimidines are thymine (pairs with adenine), uracil (pairs with adenine), and cytosine (pairs with guanine).
In RNA, there are four kinds of base: adenine, guanine, cytosine and uracil. There are no thymine bases. Therefore, there are no thymine and adenine base pairs as there are in DNA so adenine pairs with uracil.
