When insulin is initially synthesized, the polypeptide chain is too long and must have a part cleaved off. what type of regulation of gene expression is this?

Answer – Post-translational regulation

IN the case of insulin, mRNA is translated, but the polypeptide chain must be processed into a functional form by cleaving off a part. This processing after an mRNA molecule has been translated, to control gene expression in the cell before the polypeptide becomes active, is called post-translational regulation.

answer : haversian

[explanation: -(compact bone is organized as parallel columns, known as haversian systems, which run lengthwise down the axis of long bones. these columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone)]
