To replicate within the cells of a host, recombinant DNA must either _______ the host's genome or contain a(n) _______.Otherwise, the recombinant DNA will not be replicated, because DNA _______ requires specific sequences to bind to DNA.
A) integrate into; origin of replication; polymerase
B) integrate into; vector; polymerase
C) recombine with; origin of replication; ligase
D) recombine with; stop transcription signal; polymerase
E) integrate into; stop transcription signal; ligase

Recombinant DNA must integrate into the host's genome in order to replicate. It must also contain an origin of replication, which is a specific sequence that allows DNA polymerase to bind and initiate replication. Therefore, option A, which states that recombinant DNA must integrate into the host's genome and contain an origin of replication, is the best choice.

To Replicate Within the Cells of a Host, Recombinant DNA
