Answer 1

the three chemically distinct components are phosphate sugar nitrogenousbase

Answer 2

Answer:

A nucleotide has three chemically distinct components and these components will be discussed in the explanation part of the answer.

Explanation:

Nucleotide has three chemically distinct components :

• A nitrogenous base
• A pentose sugar (deoxyribose in DNA and ribose in RNA)
• The phosphate group

Purine and pyrimidine are two types of nitrogenous bases. The two major pyrimidine bases found in DNA are thymine and cytosine and in the case of RNA instead of thymine, it is uracil. The common purine bases found in DNA and RNA are adenine and guanine. Examples of nucleotides are Adenylic acid, AMP (adenosine monophosphate), dAMP(deoxyadenosine monophosphate), DCTP(deoxycytidine triphosphate).
