Ribonucleic acid is a
Answer to Problem 1MC
Correct answer:
Messenger RNA carries the genetic information of DNA from the nucleus to cytoplasm for the protein synthesis. Therefore, option (b) is correct.
Option (b) is given as “messenger RNA”.
Explanation of Solution
Justify reason for the correct statement:
There are three classes of RNA:
Hence, option (b) is correct.
Justify reasons for the incorrect statements:
Option (a) is given as “ribosomal RNA”.
Ribosomal RNA
Option (c) is given as “transfer RNA”.
Transfer RNA
Option (d) is given as “microRNA”
MicroRNA
Hence, options (a), (c), and (d) are incorrect.
The molecule that carries the genetic information for the protein synthesis from the nucleus to the cytoplasm is messenger RNA.
