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. Web31.

WebThe replication complex is the group of proteins that help synthesize the new DNA strands. A replication unit is any chunk of DNA that is capable of being replicated — e.g. a plasmid with an origin of replication (ORI) is a replication unit. Alternatively, this can also mean a region of DNA that is replicated together.
