WebFeb 5, 2003 · Chromatin, in turn, loops and folds with the help of additional proteins to form chromosomes. Condensing DNA into chromosomes prevents DNA tangling and damage during cell division. Depending on … WebEach eukaryotic chromosome consists of a long linear DNA molecule associated with proteins, forming a compact complex of proteins and DNA called chromatin. Chromatin contains the vast majority of the DNA of an organism, but a small amount inherited maternally, can be found in the mitochondria.

WebDec 21, 2024 · The two nuclear membranes (one in each half of the cell) begin to form around the chromosomes. Nucleoli reappear and the chromosomes in each soon-to-be new cell begin to decondense back into chromatin. Mitosis is complete at the end of this stage. Cytokinesis (splitting of the cytoplasm): Webchromatin is a network of DNA-binding proteins called histones. Chromosomes become highly coiled and tightly compressed packets of DNA, histones, and other proteins as a result of the coiling and wrapping of chromatin during cell division (.
