Sequence of DNA (Non- coding) is known as:
exon
intron
cistron
none
B.
intron
Intrans are DNA sequence lying within a coding sequence, i.e. Exons but not usually encoding cell product and resulting so called split genes cistron is a segment of linear DNA encoding a specific and functional product, usually protein.
