Thymine. It is replaced with Uracil.
Uracil (U) is not found in DNA and is replaced by thymine (T) in DNA molecules. Uracil is found in RNA instead of thymine.
Thymine
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.
RNA has the base uracil rather than thymine that is present in DNA, so the answer to you question is.. thymine.
The presence of uracil indicates that the molecule associated with the ribosomes is RNA. In RNA, uracil replaces thymine, which is found in DNA. Therefore, if uracil is present in the nitrogen bases of a molecule, it confirms that the molecule is RNA.
Uracil is not naturally present in DNA. Instead, it is found in RNA, where it replaces the thymine base found in DNA. Thymine is the corresponding base in DNA and is not found in RNA.
A nitrogenous base that is found in RNA but not DNA is uracil.
Thymine is not found in RNA. It is instead replaced by Uracil.
Generally the DNA molecule is double stranded to RNA's single strand. The RNA molecule uses uracil as a base while the DNA molecule uses thymine. RNA has catabolic properties that allow it to act in things such a ribosomes and tRNA. DNA is just a carrier of the genetic information.
Uracil is in RNA and Thyramine is in DNA, the other nitrogen bases are the same In RNA Adenine is complementary to Uracil and Guanine is complementary to cytocine In DNA Adenine is complementarty to Tyramine and Guanine is complentary to cytocine
The SUGAR found in DNA but not RNA is Codo.
The nitrogen containing base that is found only in RNA is uracil. It takes the place of thymine in DNA
