_ refers to the breakdown or removal of the capsid.
Correct answer: B. Uncoating
- A. Assembly
- B. Uncoating
- C. Integration
- D. Maturation
Explanation
Option A: Assembly-The stage where viral genomes and structural proteins come together inside the host cell to form new virions.Option B: Uncoating-The step where the viral capsid is disassembled after entry, releasing the viral genome into the host cell. Triggered by receptor signals, enzymes, or pH changes.Option C: Integration-The process in which certain viruses (e.g., retroviruses) insert their genome into the host's DNA, allowing long-term persistence.Option D: Maturation-Final modifications of virions to become infectious, often involving proteolytic cleavage or envelope acquisition.

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.
