How long are human cheek cells
WebOne human nucleus contains 46 chromosomes (single chromosomes during interphase). These 46 chromosomes comprise about 6 feet of DNA (2 meters). This amount of DNA was previously thought to contain about 100,000 functional genes, but that number has now been reduced to about 30,000 genes (one percent of the total DNA in the nucleus). Webcells off our cheeks. (The more vigorous and the longer that you swish, the more cells are removed, and the more materials you’ll have from which to extract DNA.) Then, we will lyse the cell membranes by adding a detergent based cell lysis solution, which allows the DNA to be freed. DNA is soluble in water, but much less soluble in alcohol.
