Introduction: DNA, Deoxyribonucleic acid, is a double stranded, helical nucleic acid molecule which determines inherited structure of a protein. The “steps” are made of bases: adenine, guanine, cytosine, and thymine. The sides are sugar and phosphate molecules. Restriction enzymes are enzymes that cut DNA at restriction sites, leaving fragments blunt or sticky. The restriction fragments are separated using a technique called gel electrophoresis. DNA has a negative charge so when an electrical charge is applied …showed first 75 words of 564 total…

We removed the gel from the gel casting tray and examined it under a light box and compared it to the ideal gel (figure1-2).
