Answer 2

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.
