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.
When growing cultures, the agar is<u> inoculated</u> to separate pathogenic colonies of organisms from colonies of normal flora.
Agar is the medium that is used for growing natural, common flora of microorganisms as the majority of the microorganisms can sustain in the agar medium.
If we want to determine a separate pathogenic colony of organisms in an agar medium then we need to inoculate the agar growth medium so that the pathogenic organism is separated from the normal flora of the microorganism. This technique allows us to filter out the cells that have the pathogenic microorganism in it.

Scientists estimate that the fishing industry kills between 0.97 and 1.97 trillion wild fish worldwide every year, further straining fragile oceans and other waterways that are already poisoned by pollution from oil spills, agricultural runoff and immense amounts of garbage.
