A) RNA pplymerase
B) DNA endonuclease
C) Exonuclease
D) DNA polymerase
Correct Answer: D
Solution :
Enzymes catalysing DNA synthesis (DNA replication) on DNA strand are DNA polymerases. They catalyse the\[S~\xrightarrow{{}}3\] polymerization. An enzyme breaking the internal phosphodiester bonds in a DNA molecule is endonuclease whereas the nuclease enzyme which starts cleavage from free-end of DNA is called exonuclease. RNA polymerase catalysing RNA synthesis during transcription.
