TRUE OR FALSE: F+ cells takes genetic information through the pilus of the F- cell.

TRUE OR FALSE: F plasmid is double stranded. When genetic information is being shared from the F+ cell to the F- cell, the double stranded is split open and a single strand is carried through the pilus to the F- cell.
