NEET BIOLOGY

Detailed explanation-1: -The lysogenic cycle: The phage infects a bacterium and inserts its DNA into the bacterial chromosome, allowing the phage DNA (now called a prophage) to be copied and passed on along with the cell’s own DNA.

Detailed explanation-2: -The lysogenic cycle definition is a viral reproductive stage where the virus’s DNA is being replicated using the host cell’s DNA. During lysogenic infection, the virus uses the host to help copy its DNA or genetic information, but it is not producing any proteins.

Detailed explanation-3: -In the lysogenic cycle, phage DNA is incorporated into the host genome, forming a prophage, which is passed on to subsequent generations of cells. Environmental stressors such as starvation or exposure to toxic chemicals may cause the prophage to be excised and enter the lytic cycle.

Detailed explanation-4: -The lysogenic cycle, or non-virulent infection, involves the virus assimilating its genome with the host cell’s genome to achieve replication without killing the host.
