Mixed together, these molecules can … WebMolecular cloning is the process of cutting out a human gene and putting it into a piece of bacterial DNA. Mitosis is the process in which a cell divides into two cells that each has the same amount of DNA as the original cell. There are some similarities between molecular cloning and mitosis, but the differences outnumber the commonalities.

WebCutting and joining DNA Molecules. Cutting DNA molecules. Before 1970 there was no method of cleaving DNA at discrete points. All the available methods for fragmenting DNA were non-specific.
