Question

Match the types of RNAs with their corresponding functions.
$\begin{array}{cc}\text{Types of RNA}& \text{Functions}\\ \text{i. tRNA}& \text{a. Primary component of ribosomes}\\ \text{ii. mRNA}& \text{b. Carries amino acid to the ribosomes}\\ \text{iii. rRNA}& \text{c. Carries information for protein synthesis}\end{array}$

• A. i-c, ii-a, iii-b
• B. i-b, ii-c, iii-a
• C. i-a, ii-c, iii-b
• D. i-b, ii-a, iii-c

Answer 1

The correct option is B i-b, ii-c, iii-a

Transfer RNA (tRNA) is the RNA molecule present in cytoplasm of cells. It carries amino acids to ribosomes for protein synthesis.
Ribosomal RNA (rRNA) is the RNA molecule which is a component of the ribosome. It helps in the function of protein synthesis.
Messenger RNA (mRNA) is the RNA molecule that carries the information for protein synthesis from the nucleus to the ribosomes.
