Match the following enzymes involved in DNA replication with their functions. - unwinds the DNA structure and makes it lay flat
- adds new nucleotides to each strand and a subunit proofreads the new nucleotides
- seals the fragments into one long strand
- makes a dent in the double helix and then begins to unzip it

DNA ligase
DNA gyrase
helicase
DNA polymerase

unwinds the DNA structure and makes it lay flat - helicase

adds new nucleotides to each strand and a subunit proofreads the new nucleotides - DNA polymerase

seals the fragments into one long strand - DNA ligase

makes a dent in the double helix and then begins to unzip it - DNA gyrase
