Group of molecules that includes thymine and cytosine?

A group of molecules that includes thymine and cytosine is pyrimidines

The two pyrimidines are composed of?

thymine and cytosine

What pyrimidines are found in DNA?

Uracil, cytosine, or thymine

What is Thymine and cytosine also called?

Thymine and cytosine are two nitrogen bases found in DNA. DNA is composed of thousands of nucleotides which are composed of one of four nitrogen bases. Both of these nitrogen bases are also pyrimidines, or they have one ring like structure See related link for more info on thymine, cytosine and pyrimidines.

What are the names of pyrimidines?

Cytosine and thymine. one is a double ring sugar while the other is a single ring suagr. They are complemetarily paired with purines.
