Question

What is an intron and why are they important?

Answer 1

Introns:

1. A nucleotide sequence in a gene that is removed by RNA splicing of the final product is known as an intron.
2. Introns are a non-coding part of nucleotide and are not highly conserved.
3. Thus, it is essential to remove the introns so that the formation of incorrect proteins stops.

Importance of introns :

1. Introns act as hot spots in the recombination in the formation of new combinations of exons.
2. Introns increase the possibility to create new genes which can result in evolution.
