HOW DOES IT WORK? This is the DNA source in this protocol. Wheat
germ comes from wheat seeds. The "germ" is the embryo, which is
the part of the seed that can grow into a new wheat plant. When
wheat seeds are milled into white flour, the wheat germ and
wheat bran are removed, leaving only starch. Wheat germ contains
many nutrients while wheat bran consists of fiber. Whole wheat
flour contains all parts of the wheat seed and is therefore more
nutritious than white flour while also providing important fiber
for digestion. The heat softens the phospholipids (fats) in the
membranes that surround the cell and the nucleus. It also
inactivates (denatures) the deoxyribonuclease enzymes (DNase)
which, if present, would cut the DNA into such small fragments
that it would not be visible. Denatured enzymes and DNA unravel,
lose their shape, and thus become inactive. Enzymes denature at
60° Celsius, and DNA denatures at 80° Celsius. Detergent
contains sodium laurel sulfate, which cleans dishes by removing
fats and protein
