Question

How can any RNA nucleotide be easily distinguished from a DNA nucleotide?

A. RNA nucleotides have a unique phosphodiester bond linkage
B. RNA nucleotides have uracil nitrogenous bases
C. RNA nucleotides have an -OH on the 2’ carbon of the ribose
D. RNA nucleotides cannot be easily distinguished from DNA nucleotides

Answer 1

The correct answer will be option-C.

Step-by-step explanation:

The Nucleic acids present in the cells are of two types: Ribonucleic acid (RNA) and the Deoxyribose nucleic acid (DNA).

These nucleic acids show distinctive differences in their structure like:

1. Sugar: The sugar in DNA lacks oxygen group at the 2' C which is present in the RNA as OH group is present.

2. Nitrogenous bases: The nitrogenous base in the DNA are adenine, guanine, cytosine and thymine whereas RNA lacks thymine and have uracil.

The main difference is the structure if sugar on the basis o which these nucleic acids have been named. Thus, Option-C is the correct answer.
