Question

The portion of phage DNA required for packing it in a capsid is retained

Answer 1

Energy stored along double-stranded (ds) DNA chains in bacteriophage capsids must facilitate injection of the genome into host cells. As a consequence, the structure and energetics of the packaged DNA in these systems are necessarily coupled. Although both have been the focus of research for decades, they are not fully characterized by any virus system.
