Which statement about recombinant DNA is true?
A) All restriction endonucleases generate blunt-end fragments.
B) Hydrogen bonds between base pairs are very strong.
C) Blunt ends are exposed bases that can hybridize with complementary sequence fragments.
D) Sticky ends prevent DNA ligase activity.
E) Restriction endonucleases cut both strands of DNA simultaneously.

Question

Quizplus · Accepted Answer

Restriction endonucleases are enzymes that recognize specific sequences of DNA and cut both strands of the DNA molecule at these sites, which is essential for the creation of recombinant DNA. This simultaneous cutting allows for the insertion or removal of DNA fragments.
