Does DNA or RNA have uracil?

Answer 1

purine.

I remember cytosine, guamine, and uracil are pyrimindine because the word pyrimidine makes me think of the word pryamid and there are THREE pyrimidines which spell the word CUT :) hope that helps :)

Answer 2

Found in Rna only, Uracil is a pyrimidine; which actually substitutes itself in Rna instead of Thymine as represented in Dna.

Answer 3

-Adenine and Guanine are purine. -Thymine, Cytosine and Uracil are pyrimidine.

Answer 4

Uracil nucleotides can be incorporated by mistake in DNA. Then it has to be repaired and replaced by a thymidine. Normaly, uracil nucleotides are found in RNA only.

Answer 5

The nucleobases Guanine and Adenine are purine bases, while Cytosine, Thymine, and Uracil are pyrimidine. G pairs up with C, while A pairs up with T in DNA and U in RNA.

Answer 6

Yes, uracil is a derivative of a pyrimidine. It is also useful to note that uracil is a naturally occurring derivative.

Answer 7

RNA has uracil. DNA has thymine in place of uracil. Both uracil and thymine pair with adenine.

Answer 8

RNA has uracil, while DNA does not. RNA uses uracil as one of its four nitrogenous bases, along with adenine, guanine, and cytosine, whereas DNA uses thymine instead of uracil.

Answer 9

purine
