Question

Name one monomer that forms nucleic acid​

Answer 1

Answer:

nucleotides

DNA and RNA are made up of monomers known as nucleotides. The nucleotides combine with each other to form a polynucleotide: DNA or RNA.

Answer 2

Answer

Nucleotide is a monomer that forms nucleic acid.

Nucleotide = Nucleoside + phosphoric acid.

❖ A nucleotide is composed of a Nucleoside and a phosphoric acid by a phosphoester bond with the liberation of a water molecule.

» Depending upon types of pentode sugar present, nucleotide are of two types :

(a) Ribonucleotides :

$\diamond$ Adenosine + H₃PO₄ = adenylic acid.

$\diamond$ Guanosine + H₃PO₄ = guanylic acid.

$\diamond$ Uridine + H₃PO₄ = Uridylic acid.

(b) Deoxyribonucleotides :

$\diamond$ Deoxy adenosine + H₃PO₄ = Deoxy adenylic acid.

$\diamond$ Deoxy guanosine + H₃PO₄ = Deoxy guanylic acid.

$\diamond$ Deoxy thymidine + H₃PO₄ = Deoxy thymidylic acid.
