To identify people by DNA it is better to make copies of non-coding segments because they exhibit more variation than genes.
- The polymorphic sequences of non-coding DNA vary between individuals in humans.
- Variable number tandem repeats, or VNTRs, are created when DNA sequences are repeatedly replicated in the genome's non-coding regions.
- It is possible to create a person's genetic fingerprint by counting the amount of repeats, which varies between individuals.
- However, this non-coding DNA is used in criminal investigations by forensic experts.
- There are distinctive repeating patterns found inside this area of DNA that can be utilized to distinguish one person from another.
- Short tandem repeats (STRs) are a type of pattern that can be measured to determine a person's DNA profile.

The true descriptions regarding muscles are; Cardiac muscles and skeletal muscles are striated, heart (cardiac) and digestive (smooth) muscles are involuntary muscles, cardiac muscles work to pump blood.

Smooth muscle are found in walls of hollow organs such as the stomach and are stimulated by involuntary action. While the cardiac muscles are found solely in the walls of the heart, they are highly specialized and under the control of of the autonomic nervous system.
