A) DNA ligase
B) DNA polymerase
C) RNA polymerase
D) Restriction endonuclease
Correct Answer: D
Solution :
Restriction endonuclease is used to cut DNA strand at specific site. These sites are called, recognition sites and therefore, these enzymes are used in genetic engineering. DNA polymerase enzyme synthesize (Polymerization) the new strand on template strands during replication. DNA fragments are joined by DNA ligase. RNA polymerase causes the synthesis of RNA on DNA template, this process is called, transcription.
