The first step in DNA replication is the separation of the two DNA strands that make up the helix that is to be copied.

It starts when a protein starts the unwinding of the DNA helix. Next comes the separation of the DNA strands right before the transfer of genetic data to the newly assembled DNA strands starts. A protein known as helicase is what breaks down the hydrogen bonds between strands of DNA during replication.

Why do wetlands have a rich supply of nutrients?
Ratling [72]
Well, first off, the sediments get brought down from the mountains after eroding away. Those sediments combine with others as it passes through the creeks and streams, rivers etc. Whatever dies, for example lets say chum salmon since they have nutrients within them. They aren't good swimmers so they are normally at the mouth of the river or in the small streams nearby. When they die, their nutrients go into the soil, that soil or whatever nutrients in that, could be swept out to the wetlands and piled up. Thus, adding rich nutrients. Adding the sediments from high up, you have a rich supply of nutrients from the wildlife that dies there as well.
