With the exception of gametes, all new somatic cells in all multicellular organisms are formed through the process of mitosis. What must occur with the DNA in the original cells in order for mitosis to make new cells?
In order for mitosis to make new cells, the DNA in the original cells must undergo replication. This process involves the duplication of the genetic material, resulting in two identical copies of each chromosome. The replicated DNA is then distributed equally between the two daughter cells during mitosis, ensuring that each new cell receives the complete set of genetic information.
