DNA sequencing is a technique used to determine the exact sequence of nucleotides in a DNA sample. Electrophoresis, a method for separating DNA fragments, is used when the DNA differs in length by only one base. DNA samples are placed in a gel and exposed to an electric...


On an electric furnace, the heat sequencer lets the heating elements receive electricity in turn rather than all at once. When the furnace first comes on, if all the heating elements could draw electricity at the same time, the resulting spike in current would trip the ...
