In order to read DNA‚ it must be sequenced. This sequencing uses electrophoresis‚ a technique that separates sections of DNA that differ by a base. Electrophoresis used to be done manually‚ but was error prone and time consuming. Now‚ automatic sequencing machines are used. A technician begins the process by pouring gel between two glass plates that are set less than half a millimeter apart. After the gel is set up‚ DNA is put into each of the ninety-six lanes. The DNA sections then move through
