Detailed explanation-1: -During interphase (1), chromatin is in its least condensed state and appears loosely distributed throughout the nucleus. Chromatin condensation begins during prophase (2) and chromosomes become visible. Chromosomes remain condensed throughout the various stages of mitosis (2-5).
Detailed explanation-2: -During S phase of the eukaryotic cell division cycle, newly replicated DNA is rapidly assembled into chromatin.
Detailed explanation-3: -During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
Detailed explanation-4: -During interphase the DNA strands are uncoiled (uncondensed) in the nucleus. This uncondensed genetic material is called chromatin; thus an uncondensed chromosome can be called chromatin.
Detailed explanation-5: -Interphase: The structure of chromatin during interphase of mitosis is optimized to allow simple access of transcription and DNA repair factors to the DNA while compacting the DNA into the nucleus. The structure varies depending on the access required to the DNA.
