Which processes take place during the lytic cycle?
Correct answer: D. All of these
- A. Replication
- B. Transcription
- C. Translation
- D. All of these
Explanation
The lytic cycle is a viral reproduction process where a bacteriophage infects and destroys a host cell. It begins with attachment, as the phage binds to receptors on the bacterial surface, followed by entry, where viral DNA is injected into the host. During biosynthesis, the viral genome hijacks the cell's machinery to produce viral proteins and nucleic acids. In the maturation stage, these components assemble into complete viruses. Finally, the host cell undergoes lysis, breaking open and releasing many new viruses to infect other cells. This cycle is rapid and always ends with the death of 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.
