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.
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.
DNA have thymine while RNA have uracil nitrogenous base.
