Which of the following components is NOT essential for DNA cloning?
A) plasmids
B) ligases
C) helicases
D) DNA fragments
E) restriction enzymes

Quizplus · Accepted Answer

Helicases are not essential for DNA cloning. The other components listed are all necessary for the cloning process; plasmids are used as vectors to carry the cloned DNA fragment, ligases join the DNA fragment to the vector, DNA fragments are the pieces of DNA that are being cloned, and restriction enzymes are used to cut the DNA at specific sites. Helicases are enzymes that unwind double-stranded DNA, but they are not required for the cloning process.
