Question

8. Of the following functions, the major purpose of RNA is to

A. transmit genetic information to offspring

B. function in the synthesis of proteins

C. make a copy of itself, thus ensuring genetic continuity

D. act as a pattern to form DNA

E. form the genes of an organism

Answer 1

Option B

The most important function of RNA is to make proteins by the process of translation. DNA cannot form proteins directly. So, it undergoes transcription to form RNA which undergoes translation to form protein. RNA is also catalytic in function for the process of protein formation.

First option is incorrect because the transmission of genetic material is primarily the function of DNA.

Third option is incorrect because RNA cannot make its copy itself. It is replicated by using DNA as a template.

Fourth option is incorrect because only some of the viruses can form a DNA copying from RNA which is called as reverse transcription.

Last option is incorrect because DNA is responsible for the formation of genes.
