Question

Which protein is responsible for unraveling the DNA double-helix into 2 strands to prepare it for copying?


Single Strand Binding Proteins


DNA Ligase


DNA Polymerase


DNA Helicase

Answer 1

single strand binding protein by peptide bond

Answer 2

DNA helicases are a group of enzymes which are responsible for unravelling the two strands of DNA to make them separate.

These separated strands can then be used for DNA replication, as one of the unravelled strands act as template.

This enzyme is therefore very important in the process of DNA replication.
