The part of the bacteriophage that enters the host cell is

Explanation

The genome of a bacteriophage enters the host cell. Here is the explanation of each of the options:1. Protein Sheath: The protein sheath of a bacteriophage is a structure that surrounds and protects the genetic material of the virus. It is not the part that enters the host cell.2. Genome: The genome of a bacteriophage is its genetic material, typically composed of DNA or RNA. This is the part that enters the host cell. Once inside the host cell, it directs the host machinery to replicate and produce more phage particles.3. Protein Coat: The protein coat, also known as the capsid, is the outer shell of the bacteriophage. It encases the genetic material (genome) of the virus. While the protein coat does play a crucial role in the attachment and injection of the genome into the host cell, it is not the part that directly enters the cell.4. Tail: The tail of a bacteriophage is involved in attaching to the host cell and injecting the genetic material (genome) into the host. It serves as a delivery system for the genome.
