NEET Biomolecules — Set 11

Question 1

Which nucleic acid is involved in protein synthesis?

Accepted Answer

RNA (ribonucleic acid) plays a key role in protein synthesis, including mRNA, tRNA, and rRNA.

Question 2

Which monosaccharide produces an optically inactive product upon reduction?

Accepted Answer

Fructose, a ketohexose, reduces to form mannitol and glucitol, but its symmetry in some contexts yields optically inactive products; it’s a reducing sugar with unique properties.

Question 3

Which disaccharide is found in sugarcane?

Accepted Answer

Sucrose, composed of glucose and fructose, is the primary sugar in sugarcane.
