The term "lysogenic induction" refers to

-switch from lysogenic to lytic growth

-decision to become a prophage

-positive autoregulation of the lambda repressor protein cI

-activation of lambda operon transcription

-stimulated growth of bacteria carrying a prophage

The correct answer would be switch from lysogenic to lytic growth.

The two cycles of viral reproduction are: lysogenic cycle and lytic cycle.

In lysogenic cycle, the viral DNA gets incorporated into bacterial or host genome and is spread with host cell reproduction or division. The viral or bacteriophage genome is called as prophage.

However, factors such as UV radiations or other chemicals can result in lysogenic induction i. e. switching of lysogenic phase to lytic phase.

During this, the viral genome is excised from the bacterial genome and is replicated, transcribed and translated in order to produce and assemble the viral offspring.

The viral progeny is then released by bursting or lysis of the bacterial or host cell.
