In order for a cell to divide successfully, the cell must first...duplicate its genetic information (DNA).
Prostaglandins are not stored in cells and are synthesized just before they are released, rapidly inactivated after their release and they are paracrine substances (Options b, c and e).
<h3>Whta are prostaglandins?</h3>
Prostaglandins are chemical substances that act as hormones by affecting surrounding cells in a tissue.
These substances (prostaglandins) are not secreted by specific glandular organs as other hormones.
Prostaglandins are substances that have fundamental functions for the normal functioning of the body.

Answer:
Explanation:
Operator region are region of DNA (deoxyribonucliec acid) that repressors protein binds to prevent transcription.
Repressor is an example of regulatory protein they regulate the rate at which transcription of operon occurs . A repressor functions when its bounded to the operator and it prevent enzyme RNA (ribonucliec acid)polymerase from moving to DNA to transcribe the nitrogenous bases by placing a complementary base pair.
Activators are other regulatory proteins that bounds to its DNA binding site and increases transcription of the operon.
