Which of the following is a correct match?
Options
- ADNA - -D-Ribose sugar
- BRNA - Protein Synthesis
- CGlucocorticoids - Hyperthyroidism
- DVitamin A - Convulsions
Correct answer
B. RNA - Protein Synthesis
Step-by-step solution
DNA contains -D-2-deoxyribose sugar, whereas RNA contains -D-ribose sugar. RNA molecules (mRNA, tRNA, rRNA) are directly responsible for protein synthesis in the cell. Glucocorticoids are steroid hormones secreted by the adrenal cortex that regulate carbohydrate metabolism and stress responses, not hyperthyroidism. Deficiency of Vitamin A causes night blindness and xerophthalmia, whereas deficiency of Vitamin B6 causes convulsions. Therefore, the only correct match is RNA - Protein Synthesis. Answer: RNA - Protein
