An enzyme that makes covalent bonds between nucleotide sequences in DNA is
A) DNA polymerase.
B) DNA ligase
C) RNA polymerase.
D) transposase.
E) DNA helicase.

Question

Quizplus · Accepted Answer

DNA ligase is the enzyme that makes covalent bonds between nucleotide sequences in DNA. It is responsible for joining the Okazaki fragments on the lagging strand during DNA replication and for joining DNA strands during DNA repair processes. DNA polymerase is responsible for adding nucleotides to the growing DNA strand, RNA polymerase is responsible for transcribing RNA from DNA, transposase is responsible for moving DNA sequences within and between chromosomes, and DNA helicase is responsible for unwinding the DNA double helix during replication and transcription.
