WebIn human interphase cells, the chromatin can be organized in the nucleus based on all of the following EXCEPT. ... In human interphase cells, chromatin organization within the nucleus is based on factors such as function, transcriptional activity, and interactions between different genomic regions. However, chromosomes do not organize strictly ... WebDuring the interphase between successive mitoses, the DNA molecule of a chromosome is doubled (replication), after which each chromosome consists of two identical sister chromatids. During mitosis, these chromatids are then separated and split so that each daughter nucleus receives an identical half as a daughter chromosome.
