What are the four bases found DNA?

adenine----The four nitrogenous bases that comprise DNA are adenine, guanine, thymine, and cytosine. there are four kinds of nitrogenous bases in dna. two of the nitrogenous bases, adenine and guanine,belong to a group of compounds known as purines. the remaining two bases, cytosine and thymine, are know as pyrimidines. Adenine pairs up with thymine, and cytosine pairs up with guanine. Humans also use a fifth base in RNA called uracil. In the case of RNA, thymine is replaced by uracil and other three bases remains the same. All of these bases are attached to the sugar and phosphate. The double helix maintains a constant width because purines always face pyrimidines in the complementary A-T and G-C pairs. And they are all connected by a phosphorous base. A-T; G-C The phosphorous base can be broken for DNA replication purposes.

Why are there four different kinds of nucleotides?

There are four different kinds of nucleotides because they contain different nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G). These bases can pair up in specific ways (A with T, C with G) to form the rungs of the DNA double helix. The sequence of these nucleotides allows for the storage and transmission of genetic information.
