PPT-PLASMIDS Plasmids are DNA molecules that exist free of the chromosome in the cell. Most

Mike . Clark, M.D.. Amount of Genetic Material in a Cell. Before we discuss mitosis or meiosis – let’s examine how much genetic material is in a cell.. There are two divisions of cells in the human body- somatic cells and gametes (sex cells).

The key is to separate the plasmids from the bacterial chromosome. This is not trivial, since they are both DNA. What is the difference?.
