All eukaryotic genes contain two kinds of base sequences. Which of the following plays role in protein synthesis ?

  • Introns

  • Exons

  • Electrons

  • Both (a) and (b)

Solution

B.

Exons

All eukaryotic genes contain two kinds of base sequences ie, introns and exons. Exons are the coding regions which are interrupted by non- coding regions, that is, introns. Exons consist of the information which is required to encode a protein. Introns are removed to make a functioning messenger RNA that can be translated into a protein.
