Which of the following statements best desaribes a feature of the lysogenic cycle of lambda (A) phage? a) After infection, the viral genes immediately turn the host cell Into a phage-producing factory, and the host cell then lyses b) Most of the prophage genes are activated by the product of a particular prophage gene c) The phage genome replicates along with the host genome d) Certain environmental triggers con cause the phage to exit the host genome, switching from the lytic to the lysogenic e) The phage DNA is incorporated by crossing over into any nonspecific site on the host cell's DNAExplanation / Answer
Answer 1. Mutation is the correct option. First step towards genetic variation is mutation which can create entirely new alleles in a population.
Answer 2. The correct option is B.
Answer 3. The correct option is genetic uniformity (low number of allele variants). Drift increases the inbreeding coefficient and increases homozygosity as a result of removing alleles from a population.
Answer 4. Essentialism --> Aristotle
5. Essay on population --> Malthus
6. Uniformaltariatism --> Lyell
7. Transformism --> Lamarck
8. Adaptive Radiation --> Darwin
Answer 9. The correct option is A. Lysogenic cycle is characterized by the large numbers of phage production in the host cell that eventually leads to the lysis of host cell.
