WebThis is what it enters into. But if the cell checks it and it says you're big enough you're ready to replicate. It goes onto the S. Phase and this is the DNA replication phase. And so the sister chroma tides are made here because they are the copy of the same chromosome. So you have a chromosome here and it gets replicated. WebWhen a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication.

WebOct 7, 2024 · Step 1: Replication Fork Formation. Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands. DNA has four bases called adenine (A), thymine (T), … WebAny accidental changes in chromosome structure will be permanent. These changes will be passed on through future rounds of DNA replication. Therefore any loss of DNA is a serious problem. If the end of a DNA strand is not copied each time the DNA is replicated then the chromosome will shrink continuously as the cell cycle continues.
