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.

<span>USGS is gathering information in the Arctic Ocean to study acidification and identify a baseline of information about the ocean's chemistry. This chemistry is expected to change due to decreases in the amount of summer sea ice.</span>
B.
Passive transport doesn't requireenergy (ATP), active transport doesrequire energy. Passive transport moves molecules WITH the concentration gradient (high to low), while active transport moves molecules AGAINST the concentration gradient (Low to High).
