Initiation of... 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. chw workers
