An example of a single gene that can encode two completely different proteins is:
Integrase |
||
Levi and Strauss |
||
Calcitonin |
||
Caspase |
Answer:
calcitonin
Explanation:
In the calcitonin gene alternative RNA processing leads to the
production of different protein products.
1. The gene CGRP (Calcitonin Gene Related Peptide): In the brain,
if cleavage occurs after the sixth exon then
calcitonin-gene-related peptide is produced.
2. Hormone calcitonin: If cleavage and polyadenylation occur in the
thyroid gland, after the fourth exon then hormone calcitonin
produced.
Therefore, it depends on the splicing in which 3′ cleavage site is
used.
