Which statement about DNA replication is FALSE?
A) The lagging strand is made of a series of pieces that must be joined together to make a continuous strand.
B) DNA replication of parental DNA is separated during replication.
C) DNA ligase adds nucleotides to the lagging strand.
D) Because the two strands of parental DNA run in opposite directions, the new strands must be made in different ways.

What happens to the packaged DNA of a specialized transduced phage when it infects a new recipient cell?
A) The DNA is chewed up by enzymes found in the recipient cell.
B) The host DNA integrates, with the prophage, into the new recipient chromosome.
C) The DNA begins to replicate without integrating into the host chromosome.

How does specialized transduction differ from regular transduction?
A) The prophage is not excised during specialized transduction.
B) The resulting bacteriophage from specialized transduction does not contain any viral DNA.
C) The resulting bacteriophage from specialized transduction cannot infect a new host cell.
D) The prophage in specialized transduction carries with it pieces of the host chromosomal DNA.
