Question

An ideal vector must integrate stably into the host genome as which structural entity?

Options

• A plasmid-independent episome

• A transposon element

• A ribosomal satellite

• An independent replicon

Answer 1

An ideal vector must integrate stably into the host genome as an independent replicon. This means the inserted DNA can replicate autonomously within the host cell, ensuring the foreign genetic material is maintained through cell divisions.
