NEET BIOLOGY

Detailed explanation-1: -The lytic cycle: The phage infects a bacterium, hijacks the bacterium to make lots of phages, and then kills the cell by making it explode (lyse).

Detailed explanation-2: -In a lytic cycle, the virus introduces its genome into a host cell and initiates replication by hijacking the host’s cellular machinery to make new copies of the virus. Once infection is complete, the newly replicated and assembled virus particles are released through lysis of the host cell into the surrounding waters.

Detailed explanation-3: -One of the two cycles of viral reproduction is the lytic cycle. It destroys the infected cell and its membrane. In this, the DNA of a virus prevails as a distinguished free-floating molecule inside the cell of bacteria and is replicated distinctly from the DNA of the host bacteria.

Detailed explanation-4: -The lytic cycle involves four steps: infecting a host (an action called exposure), injecting a cell with the virus’s genetic material, using the cell’s metabolic engines to create new viruses, and finally, weakening the cell walls until the host cell lyses, or bursts open from excessive internal pressure.
