WebHomologous, Duplicated Chromosomes. This replicated DNA molecule, in its condensed form, is now referred to as a chromosome. But, remember, there are two copies attached to each other until the genetic material is … 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.

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.
