Which of the following statements about recombinant DNA is true?
A) Recombinant DNA techniques often make use of restriction enzymes.
B) Recombinant DNA molecules are formed when a DNA molecule attaches to the bacterial cell wall.
C) Recombinant DNA molecules always contain human DNA.
D) Recombinant DNA molecules result when DNA is transcribed.
E) Recombinant DNA molecules are formed when DNA from at least three different organisms are joined together.

Question

Quizplus · Accepted Answer

Recombinant DNA techniques often make use of restriction enzymes to cut DNA at specific sites and combine it with other DNA pieces.

Answer: B, C, D, and E are all false statements. 
 Recombinant DNA molecules are not formed by attaching to the bacterial cell wall or containing only human DNA. They also do not result from transcription, but rather from the process of genetic engineering. Recombinant DNA molecules can be made from DNA from two or more organisms, but not necessarily three as implied in choice E.
