• intron

• replicon

• none of these

Answer 1

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

Explanation:

In eukaryotic genes, an intron is a non-coding “intervening” sequence that interrupts the actual instructions for building a protein. During the process of transcription, the entire gene is copied into a pre-mRNA molecule, but before it can be used to make a protein, these introns are “spliced” or cut out. The remaining segments, called exons, are then joined together to form the mature messenger RNA (mRNA) that carries the final code for translation.
