Reproduction of φ×174, a single-stranded DNA phage, involves several steps. A few statements are given below to explain the mechanism: A. The single-stranded φ×174 DNA is converted into a double-stranded replicative form (RF). B. Replication of the double-stranded replicative form results in the production of single-stranded phages, about 50% of which are +ve sense phages and the remaining are -ve sense phages. C. Replication of the double-stranded replicative form results in the production of only -ve sense phages. D. Replication of the double-stranded replicative form results in the production of only +ve sense phages. Choose the option that correctly describes the process.
