3 0

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 you hit your elbow and say that you hit your "funny bone," you have actually hit a nerve that runs across the bone surface.

frutty [35]

This bone can be found over the HUMERUS.
The funny bone of the elbow is the ulnar nerve. The nerve runs from the neck to the hand where it is connected with several muscles in the hand and in the forearm. The ulnar nerve is protected by bones, muscles and ligaments.
