DNA must be replicated before mitosis so that both identical daughter cells contain the same amount of genetic material as the parent cell once it has split in two. Helicase is an enzyme necessary at the initiation of DNA replication to unwind/unzip the DNA so that this process may begin.

Answer:

12th May at 4.17 PM

Explanation:

This is because this is during the low tides and the low tide is at its lowest, at -0.7, m than any other date or time of the month. This means that most of the shoreline has receded deep into the ocean and exposed most of the continental shelf than any other time. This leaves rooms for more sea shells to be exposed and easily collected.
