DNA contains two types of nitrogen bases. There are the purines, which include Adenine and Guanine, and the pyrimidines, which include Thymine and Cytosine.
Adenine ALWAYS bonds with Thymine, and Guanine ALWAYS bonds with Cytosine, unless, of course, we have a mutation.

Which nitrogen base of DNA cahnges?
The nitrogen base thymine in DNA is replaced by the nitrogen base uracil in RNA.
What is a molecule found in all DNA and RNA bases?
The nitrogen bases themselves are molecules. DNA and RNA both contain the nitrogen bases adenine, guanine, and cytosine. DNA contains the nitrogen base thymine, while RNA contains the nitrogen base uracil instead.
3 DNA does NOT contain the nitrogen base?
DNA does not contain uracil. RNA does!! DNA contains guanine binds with Thymine in DNA RNA contains guanine that binds with uracil DNA does not contain uracil. RNA does!! DNA contains guanine binds with Thymine in DNA RNA contains guanine that binds with uracil
WhatThree nitrogen bases that are found in DNA and RNA?
DNA and RNA both contain in all four nitrogen bases. classified into purines and pyrimidines. DNA and RNA in common have Thymine, cytosine and Guanine as the three nitrogen bases. DNA has adenine and instead of adenine RNA has uracil as the fourth nitrogen base.
What base is found exclusively in RNA?
RNA does not contain deoyribose, as DNA does, but instead uses ribose.
What is the base of nitrogen DNA?
The nitrogen bases for DNA are adenine, guanine, cytosine, and thymine
What base dose RNA have that DNA dose not have?
uracil
Does a gene contain uracil?
The nitrogen base uracil is not present in DNA. It is only present in RNA and is used as a substitute for thymine
What base is missing on RNA and what other base replaces it?
No nitrogen base is missing. You may be referring to the fact that DNA contains the nitrogen base thymine, while RNA contains the nitrogen base uracil. They both contain adenine, cytosine, and guanine.
True or false Only DNA molecules contain the nitrogen base called uracil?
No. only RNA uses uracil.
Which nitrogen base is missing in DNA?
Uracil.
What nitrogen base is in DNA but not in RNA?
thymene
