There are many ways to analyze DNA. Some popular methods include Gel Electrophoresis and Restriction Enzymes. The main purpose of Gel Electrophoresis is to separate DNA samples by size. The samples are attracted to the (+) end of the well, so they move in that direction. The smaller sized samples move quicker than the large ones, making it easy to distinguish by size. The use of restriction enzymes is to cut DNA at specific recognition sequences. The DNA is digested by some type of enzyme (for example EcoRI) and is fragmented into several sizes at specific sites.
