Answer:
Gel electrophoresis
Explanation:
Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
DNA carries all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein. In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).
E Coli bacterium are about 2.0 micrometers in length and .25 to 1 micrometer in diameter. In comparison, a red blood cell is about 6 to 8 micrometers in diameter and a thickness that ranges from .8 to 1 micrometer in the center to 2 to 2.5 micrometers at the thickest point.
