Answer:
DNA helicase is a protein type biological molecule
DNA helicase:
- DNA helicases are a class of motor proteins.
- It functions to generate the transient single-stranded DNA required as intermediates in DNA and RNA metabolism.
- The DNA Helicase is composed of 3 polymers that contain 14 chains (454 amino acid residues long).
Role of DNA helicase:
- DNA helicases catalyze the disruption of the hydrogen bonds that hold the two strands of double-stranded DNA together.
- This energy-requiring unwinding reaction results in the formation of the single-stranded DNA required as a template or reaction intermediate in DNA replication, repair and recombination.
