In RNA, the nitrogenous bases change and there is no longer Thymine, instead Uracil replaces Thymine but it bonds with the same base pair ( Adenine) as it would in DNA. In other words DNA base pairs are : Adenine- Thymine, Guanine-Cytosine. RNA base pairs are : Adenine- Uracil, Guanine-Cytosine.

What base is found DNA but not in RNA?

Thymine


Does DNA or RNA contain thymine?

No, RNA does not contain thymine. Thymine is a nitrogenous base found in DNA, but in RNA, thymine is replaced by uracil.


What is the base of RNA in place of thymine which bonds with adenine?

The nitrogen base uracil takes the place of thymine in RNA. So in RNA, uracil pairs with adenine.


What nitrogen containing base found in DNA but not in RNA?

Thymine is the nitrogen-containing base found in DNA but not in RNA. In RNA, thymine is replaced by uracil.


A nitrogen base in RNA that is complementary to thymine is?

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.


What is a pyrimidine base found in RNA but not in DNA?

Thymine


Does RNA has the nitrogen base thymine?

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. Addtional answer: The complimentary base of adenine in RNA is uracil which is a unmenthylated form of thymine. When menthylation occurs it becomes thymine which is paired with adenine in DNA. Thymine can also be called 5-methyluracil because it becomes thymine when methylation of uracil occurs at the 5th carbon.


One DNA base not normally present in RNA is?

One difference between DNA and RNA is that DNA has a nitrogen base pyrimidine thymine that connects with purine adenine. In RNA, thymine is replaced by another pyrimidine called uracil.


What nitrogen base is complementary to adenine?

Thymine nitrogen base is complementary to Adenine.


What base is not present in the nucleotides of RNA?

RNA has the base uracil rather than thymine that is present in DNA, so the answer to you question is.. thymine.


What do DNA and RNA have?

RNA has the base uracil which replaces the thymine base of DNA.


What do DNA have and RNA not?

RNA has the base uracil which replaces the thymine base of DNA.
