Answer 2

Answer:

The process is sometimes called “DNA testing” or “DNA profiling”, but signals the same process. Early DNA fingerprinting was developed in the years before the whole human genome had been sequenced. DNA fingerprinting typically relies on short tandem repeats (STRs), which are unique to individuals. These sections of DNA can be compared between two different samples. If they show the same pattern after gel electrophoresis, it indicates that the samples are from the same source.

A DNA fingerprint looks something like the columns on the paper below. On this paper, each dark band represents a fragment of VNTRs – and each column is a different tissue sample. A match would be indicated by two columns whose VNTRs patterns matched precisely.
