Q. 19. Which of the following are the functions of RNA?
(a) it is a carrier of genetic information from DNA to ribosomes synthesizing polypeptides
(b) it carries amino acids to ribosomes
(c) it is a constituent component of ribosomes
(d) All of the above
Ans. (d). rRNA, mRNA and tRNA are major classes of RNAs that are involved in gene expression.
rRNAs bind protein molecules and give rise to ribosomes.
mRNA carries coded information for translation into polypeptide formation.
tRNA is called soluble or adaptor RNA and carries amino acids to mRNA during protein synthesis.
