Coding versus Template Strands: The RNA genome of phage Qb is the nontemplate strand, or coding strand, and when introduced into the cell it functions as an mRNA. Suppose the RNA replicase of phage Qb synthesized primarily template-strand RNA and uniquely incorporated this, rather than nontemplate strands, into the viral particles. What would be the fate of the template strands when they entered a new cell? What enzyme would have to be included in the viral particles for successful invasion of a host cell?
