A sample of DNA is taken from blood of saliva. PCR makes lots of copies, or amplifies the DNA. We then add restriction enzymes to cut the DNA at palindrome sequences. We then run the DNA through gel Elecrophoresis. Each person has unique short tandem repeats that cause a unique number of cuts by the restriction enzyme. These cuts are separated by size on gel electrophoresis, so no two people have the exact same pattern. We can compare individuals banding patterns to what is found at a crime scene, taken in previous samples, in a baby, and the sample that matches all the banding patterns will be the individual.

Sergio [31]

The name of an organism that is used in general conversation is called the  Binomial name.

<h3>What is binomial name?</h3>

Binomial nomenclature, also known as binominal nomenclature or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, though they can also be based on words from other languages. It is also known as the "two-term naming system" or "binomial nomenclature." A name of this type is referred to as a Latin name, a binomial name (which is also abbreviated to just "binomial"), a binomen, a binominal name, or another type of scientific name.

The generic name, which makes up the first part of the name, indicates the genus to which the species belongs, while the specific name, also known as a specific epithet, identifies the species within the genus. For instance, the species Homo sapiens and the genus Homo both contain contemporary humans.
