Question

If the gene that produces helicase were mutated so that the helicase enzyme was non-functional, what would be the direct result?

Answer 1

DNA would not be able to be replicated.

Helicase is a crucial enzyme that is involved in DNA replication. Its main job is to unwind the DNA double helix, separating it into two strands to be replicated. This process occurs in the initiation stage of DNA replication. Without helicase, the DNA strands would not unwind properly and the process would come to a halt.
