WebA diploid cell starts with 2N chromosomes and 2X DNA content. After DNA replication, the cells is still genetically diploid (2N chromosome number), but has 4X DNA content because each chromosome has replicated its DNA. Each chromosome now consists of a joined pair of identical sister chromatids. 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.
