Question

Give one functional difference between mRNA and tRNA.

Answer 1

mRNA possesses a primary structure similar to a portion of one DNA strand and does not show any secondary or double helical structure at all. It forms a template for protein synthesis. On the other hand, the tRNA molecules of a cell act as vehicles that pick up amino acids scattered throughout the cytoplasm and transport them to specific codons of mRNA molecules on ribosomes. The tRNA molecule consists, about 80 nucleotides and is held in a clover leaf shape by hydrogen bonds between some of its nitrogenous bases.
