Restriction Enzymes
RNA polymerase is the protein that unwinds and opens up the DNA double helix to initiate transcription of mRNA by reading and copying the DNA sequence into RNA.
During transcription, the enzyme RNA polymerase opens the DNA double helix to expose a segment of the DNA that will be transcribed into RNA.
restriction endonuclease and exonuclease
The enzyme is RNA polymerase.
DNA molecules. A strand of DNA molecules can be cut to have blunted ends or jagged ends (sticky ends).
The enzyme responsible for cutting DNA molecules is called a restriction enzyme.

The enzyme helicase.
restriction endonuclease and exonuclease
DNA replication is a process during which DNA double helix opens like a zipper , new nucleotides are added along both strands of DNA by enzyme DNA polmerase and at last two molecules of DNA are formed. It takes place in S phase of interphase .
The enzyme is RNA polymerase.
DNA molecules. A strand of DNA molecules can be cut to have blunted ends or jagged ends (sticky ends).
DNA polymerase
After the enzyme passes the end of the DNA, the replication process is completed with the synthesis of a short RNA primer that is later replaced with DNA nucleotides by another enzyme called DNA polymerase. This results in the completion of a full DNA strand.
DNA polymerase is the enzyme responsible for replicating DNA by adding complementary nucleotides in the correct sequence during DNA synthesis.
