Guida verificata passo dopo passo1
Understand the structure of a bacteriophage: A bacteriophage is a virus that infects bacteria. It typically consists of a head (capsid), which contains the genetic material, a tail, and tail fibers.
Identify the function of each part: The capsid protects the genetic material, the tail helps in injecting the genetic material into the bacterial cell, and the tail fibers assist in attaching the bacteriophage to the bacterial surface.
Focus on the infection process: During infection, the bacteriophage attaches to the bacterial cell using its tail fibers.
Determine what enters the bacterial cell: The bacteriophage injects its genetic material, which is usually DNA, into the bacterial cell through the tail.
Conclude which part enters the cell: The DNA from the bacteriophage is the part that enters the bacterial cell, not the capsid, tail fibers, or envelope.
