Detailed explanation-1: -So, the correct option is ‘RNA polymerase’
Detailed explanation-2: -Final answer: DNA Ligase is not involved during DNA replication on the template with polarity 3’ → 5’.
Detailed explanation-3: -DNA replication requires other enzymes in addition to DNA polymerase, including DNA primase, DNA helicase, DNA ligase, and topoisomerase.
Detailed explanation-4: -DNA Polymerase: It helps in the replication of double-stranded DNA into two identical DNA molecules. Helicase: It helps in the separation of double-stranded DNA into single strands allowing each strand to be copied. Ligase: It acts as glue by joining 2 DNA fragments to form a new DNA strand.
Detailed explanation-5: -The order of enzymes in DNA replication include the following: DNA helicase, RNA primase, DNA polymerase, and finally DNA ligase. During the process of DNA replication, the double helix unwinds with the help of the enzyme DNA helicase.
