Question

Adenine, thymine, guanine, and cytosine are the _______ that make up the nucleotides of DNA

Answer 1

Answer:

here you go

Explanation:

There are four nitrogenous bases found in DNA that are called guanine, adenine, thymine and cytosine. They are abbreviated by the first letter in their name, or G, A, T and C. The bases can be divided into two categories: Thymine and cytosine are called pyrimidines, and adenine and guanine are called purines.

Answer 2

These are actually nitrogenous bases. According to Watson and crack model the two strands of DNA twisted around each other having double hydrogen bonds between Adenine and Thymine (A=T)and triple hydrogen bond between Guanine and Cytocine.
DNA have thymine while RNA have uracil nitrogenous base.
