Final answer:
Helicase is an enzyme involved in unwinding and separating DNA strands during replication using ATP, not in renaturing them, which makes the statement false.
Step-by-step explanation:
The statement that helicase uses ATP in order to renature DNA is false. Helicase is an enzyme that unwinds the DNA helix during DNA replication by breaking the hydrogen bonds between the nucleotide bases. Its primary function is to separate the two annealed nucleic acid strands, which is essential for copying the DNA.
ATP is used as the energy source for this process. Renaturing DNA is the process where separated DNA strands re-anneal or rejoin, which does not involve helicase.
Helicase is an enzyme that helps to open up the DNA helix during DNA replication by breaking the hydrogen bonds. It does not use ATP to renature DNA. ATP is used by other enzymes like DNA polymerase and DNA ligase. Helicase separates the DNA strands at the origin of replication, allowing other enzymes to replicate the DNA strands.
