Solution
The correct option is A Lysogeny
The lysogenic cycle is a method by which a virus can replicate its DNA using a host cell. In the lysogenic cycle, the DNA is only replicated and not translated into proteins. During lysogenic cycle the phage DNA gets integrated into host genome. The DNA is then replicated when the bacteria undergo cell division. Because all DNA is made of the same base molecules and viral DNA is no exception, the same chemical reaction that replicates bacterial DNA can replicate viral DNA. During this process host cell lysis does not occurs and multiplication of virus also does not happen because only DNA multiplication occurs without capsid proteins. If the conditions are no longer right for the lytic cycle, the lysogenic cycle resumes. So the correct answer is 'lysogeny'.
