Question

Which sequence correctly summarises the process of repression?

विकल्प

• Substrate present → genes ON → enzyme made

• Product excess → genes OFF → enzyme not made

• Substrate present → genes OFF → enzyme not made

• Product excess → genes ON → enzyme made

Answer 1

Repression follows the sequence: product excess → genes OFF → enzyme not made. The excess end product (co-repressor) helps the repressor block transcription.
