The best answer is A.
In a lysogenic cycle, the viral DNA or RNA enters the cell and integrates into the host DNA as a new set of genes called prophage. The prophage is passive and non virulent and does not destroy the cell. However if the prophage undergoes any stress or mutation or is exposed to UV radiation, it may adopt the lytic cycle and become infective.
In a lysogenic infection, there are no viral symptoms and it occurs after the viral infection is over. But the viral DNA or RNA remains in the cell and may remain there permanently .
Answer:
During interphase, centrosomes are duplicated.
Explanation:
Interphase is one of the two phases of cell cycle (other being mitotic phase).
Interphase is characterized by cell growth and DNA replication. It is subdivided into:
• G1 phase (the first gap phase) - the cell grows and becomes larger and copies organelles
• S phase – DNA and microtubule-organizing structure-centrosome are duplicated.
• G2 phase - proteins and organelles are formed.
G2 phase is followed by the beginning of mitotic phase.
