In eukaryotic genes, coding sequences are called :

A

introns

B

operons

C

exons

D

cistrons

Text Solution

Verified by Experts

The correct Answer is:
C
In split genes coding region is called exons . In higher organisms (eukaryotes) gene is not continuous , within a single gene there may be four or five silent regions . These regions are called introns (which do not transcribe mRNA) . The remaining part is called as exons (transcribr temporary complementary pairing with three bases on mRNA).
