RNA polymerase

All three enzymes are needed
|
Detailed explanation-1: -RNA polymerase is an enzyme that transcribes RNA from DNA; it is not essential for DNA replication.
Detailed explanation-2: -Final answer: DNA Ligase is not involved during DNA replication on the template with polarity 3’ → 5’.
Detailed explanation-3: -Mitochondrial RNA polymerase is needed for activation of the origin of light-strand DNA replication. Mol Cell.
Detailed explanation-4: -DNA replication requires other enzymes in addition to DNA polymerase, including DNA primase, DNA helicase, DNA ligase, and topoisomerase.
Detailed explanation-5: -RNA polymerase is one of the polymerases that don’t require a primer. Instead of a primer, RNA polymerases require special proteins called transcription factors to bind to the promoter and enhancer regions of the DNA upstream of the target area that will be transcribed.
