A bacteriophage is attached to the receptor site on the host cells:
Correct answer: C. Cell membrane
- A. Slime
- B. Cell wall
- C. Cell membrane
- D. Envelope
Explanation
A bacteriophage is a virus that infects bacteria. It attaches to the receptor site on the host cell's cell membrane. The receptor site is a specific molecule on the cell membrane that the bacteriophage can recognize and bind to.Once the bacteriophage has attached to the receptor site, it injects its DNA into the host cell. The DNA then takes over the host cell's machinery and starts to replicate itself. The replicated DNA then produces new bacteriophage particles, which are released from the host cell.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
