DNA replication Process

components involved during DNA replication process :

    1. DNA template
    2. Enzymes :
      • Helicase - unwound the two strands of DNA

      • RNA primase - Synthesis the Primer to initiate the replication process and attract RNA nucleotides which bind to the DNA nucleotides of the 3'-5' strand due to the hydrogen bonds between the bases.
      • DNA polymerase - read an intact DNA strand as a template and uses it to synthesize the new strand.

      • Ligase -  joining of Okazaki fragments during replication.
