Restriction enzymes are useful in creating recombinant DNA molecules because they
A)generate "sticky ends" by cutting at the same sequence in any DNA source.
B)are found only in human cells,where they naturally mend broken DNA strands.
C)are used to encapsulate and transport foreign DNA into cells of the target organism.
D)stimulate DNA amplification so that the desired cells or their products can be scaled up.

Question

Quizplus · Accepted Answer

Restriction enzymes cut DNA at specific sequences, generating "sticky ends" with overhanging single-stranded regions that can base-pair with complementary sequences on other DNA molecules. This property allows for the creation of recombinant DNA molecules by joining foreign DNA to a vector that has been cut with the same restriction enzyme. The resulting hybrid molecule can then be used to transform host cells, which will incorporate the foreign DNA into their genome.
