What are the 4 nitrogenous bases?

Answer 1

There are millions of "bases" and "millions" containing nitrogen but you are probably referring to the 5 involved in De-oxyribo Nucleic Acid (DNA) and Ribo-Nucleic Acid RNA. These are the so called rungs of the ladder and for DNA are Thymine, Adenine, Cytosine and Guanine. In RNA, thymine is replaced by Uracil so this is the fifth. This is one of the fundamental differences between RNA and DNA. The other is the use of Ribose instead of Deoxy-Ribose. Amongst the viruses there are both double stranded RNA and single stranded DNA so the number of strands has nothing to do with a substance being DNA or RNA.

Answer 2

Adenine, guanine, cytosine, and thymine are the nitrogenous bases for DNA. Uracil is a nitrogenous base in RNA and replaces thymine. thymine, adenine, guanine, cytosine :)

Answer 3

cytosine, thymine, guanine, adenine, and uracil.

Answer 4

I think it is adenine, guanine, cytosine, uracil, and thymine.

Answer 5

• A- adenine
• G- guanine
• C- cytosine
• U- uracil
• T- thymine
