That’s because your DNA contains the genetic code that determines what you look like, how your body works and how well you resist diseases. You receive a copy of each of your parent’s DNA -- this determines your genetic makeup. Translation is the second of two steps that turn DNA into you. WebLigase enzymes are then used to rejoin DNA strands at the ‘sticky ends’. Plasmids are the loops of DNA that can be found in the cytoplasm of bacteria. They can pass from one bacterial to another - therefore scientists tend to use them as vectors, as they carry DNA into the bacterium. Benefits and Risks asisa data
