Eukaryotic chromosome during interphase
WebIn eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase. During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into … A centromere is the central region of a chromosome itself, while the … Prior to S-phase each chromosome is a single chromatin fiber. During S-phase … Image of a cell undergoing DNA replication (all the chromosomes in the nucleus are … WebUnderstanding: Eukaryotic chromosomes are linear DNA molecules associated with histone proteins. Eukaryotic DNA is linear and associate with histone proteins in a structure called the nucleosome. During interphase, the DNA is not super-coiled into chromosomes; it is in a loose form called chromatin.

WebInterphase is the longest stage of the cell cycle and can be divided into 3 phases: G1 phase, S phase, G2 phase. The newly formed cell matures during the G1 phase. If the cell is going to divide, it enters the S (synthesis) phase where the DNA is replicated and the G2 phase where more growth occurs. What are the stages of the cell cycle?
