Question

Write a short note on deoxyribo-nucleotides.

Answer 1

Deoxyribo-nucleotides:

Deoxyribonucleotides are the substances that are used to form genetic material DNA by polymerization.

DNA is a polymer that is consisted of monomers like Deoxyribonucleic acid or deoxyribonucleotide.

This deoxyribonucleotide has three parts:

• The sugar - The sugar moiety of deoxyribonucleotide is deoxyribose. It has oxygen less than the normal sugar ribose.

• The nitrogen base - Nitrogen bases that are attached to the carbon atom of the sugar are adenine, guanine, thymine, cytosine. Attachments of one of these four nitrogen bases with sugar give rise to one kind of the four kinds of Deoxyribonucleoside.

• The phosphate moiety - Phosphate moiety attaches with either 3 or 5 carbon of Deoxyribonucleoside to form Deoxyribonucleotide or Deoxyribonucleic acid.
