Which of the following are components ofnucleotides?(a) deoxyribose(b) amino acids(c) phosphate(d) enzymes(e) organic bases

The components of nucleotides are:

(a) Deoxyribose: Yes, this is a component of nucleotides. In DNA, the sugar is a deoxyribose, which is a pentose sugar. It is called deoxyribose because it is a deoxygenated sugar, meaning it is missing an oxygen atom.

(b) Amino acids: No, these are not components of nucleotides. Amino acids are the building blocks of proteins, not nucleotides.

(c) Phosphate: Yes, this is a component of nucleotides. A phosphate group is attached to the 5' carbon of the sugar and is involved in the formation of the phosphodiester bond between two nucleotides.

(d) Enzymes: No, these are not components of nucleotides. Enzymes are proteins that speed up chemical reactions in the body, they are not part of the nucleotide structure.

(e) Organic bases: Yes, these are components of nucleotides. There are four types of nitrogenous bases in DNA: adenine (A), guanine (G), cytosine (C), and thymine (T). In RNA, uracil (U) is used instead of thymine.
