Question
Name the major enzymes involved in DNA replication.
✓
Answer
The enzymes participating in DNA replication are as follows : (i) Helicase enzymes : Open the double helix of DNA. (ii) S.S.B. proteins keep the position stable by associating with single stranded binding proteins. (iii) Topoisomerase enzymes : Reduce the coiling tension. (iv) RNA polymerase or primase enzyme (R.N.A. primer) : make small part of RNA to process DNA synthesis. (v) DNA polymerase III enzyme : work to advance the primer in 5'-3' direction. (vi) DNA Polymerase I : Fills the spaces found between the DNA. (vii) Ligase enzymes : Join the DNA fragments. (viii) Endonuclease and exonuclease enzymes : work to connect the correct nucleotides.
