In order to distinguish the DNA of one person from another, scientists often rely on the presence of short tandem repeats (STRs). These consist of short DNA sequences that are repeated many times in a row. Why are STRs useful for identification

Which of the following characteristics of short tandem repeat sequences (STRs) in DNA makes them useful for forensic as well as paternity analyses? 1. The DNA sequences within the STRs can vary significantly from individual to individual. 2. The number of repeats at STR loci is the same in everyone. 3. Every racial and ethnic group has inherited different short tandem repeats. 4. The number of repeats is highly variable from person to person.

Much of the human genome consists of repetitious DNA. Describe the difference between microsatellite and minisatellite DNA. How is this repetitious DNA useful for identifying individuals by the technique of DNA fingerprinting?
Sri K.
DNA fingerprinting focuses on the so-called "junk DNA," the noncoding parts of the DNA strand that are highly variable among individuals. Why is it important that DNA fingerprints are made from these parts and not others?
