Mitosis in a Nutshell

Yes, there is chromosome replication in mitosis. During the interphase stage of mitosis, the DNA in the cell's chromosomes replicates to form identical sister chromatids. This replication ensures that each daughter cell produced during mitosis receives a complete set of genetic information.

To find more information about chromosome replication in mitosis, you can refer to reliable sources such as scientific textbooks or reputable websites. One such resource is the University of Illinois at Chicago's Biology 100 course website, which provides detailed information about mitosis. By visiting the website (http://www.uic.edu/classes/bios/bios100/lecturesf04am/lect16.htm) and scrolling down to the section titled "Mitosis in a Nutshell," you will find a concise explanation of how chromosome replication occurs during mitosis.
