Question

During dna replication when unwinding of the interwined double helix occurs the enzymes that can break and reseal one strand are called

Answer 1

enzyme called DNA helicase

Answer 2

DNA replication

Explanation:

• The enzyme which is used to unwind DNA is the DNA helicase enzyme, which belongs to the class Helicase and is important for all organisms.
• It moves along the double-stranded DNA and separates the strands by breaking hydrogen bonds at the expense of energy from ATP.
• DNA ligase is a specific type of enzyme, a ligase facilitates the joining of DNA strands together by catalyzing the formation of phosphodiester bonds.
