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.

In which phase of meiosis do the chromosomes replicate?

WebPrior to S-phase each chromosome is a single chromatin fiber. During S-phase the DNA is replicated and this results in two chromatin fibers (known as sister chromatids). However, these chromatin fibers are attached to each other at the centromere and together they make up a post S-phase chromosome. WebDec 11, 2024 · Eukaryotic DNA replication occurs in the context of chromatin.
