Question

An intervening sequence in a eukaryotic gene that is not an active part of the gene is called a

• A. exon
• B. intron
• C. replicon
• D. none of these

Answer 1

The correct option is B intron

Gene is the chromosomal segment that is a part of DNA. Gene acts as genetic material and carries information from one generation to another. The gene structure of two units i.e., introns and exons. Introns are the non-coding part of the gene which does not code for any proteins but helps in stabilization of mRNA through splicing (removal of introns). Exons are the coding and active region of the gene which codes for different proteins.

So, the correct option is 'Intron'.
