Question

dna regions that do not code for proteins:
○ make up a limited portion of human dna.
○ have no function.
○ can be used to uniquely identify individuals.
○ are segregated on a few chromosomes.
○ are too similar from person to person to be used in str analysis.

Explanation:

Non-coding DNA regions (e.g., STRs) have high variability between individuals. This uniqueness allows them to be used in DNA fingerprinting for individual identification. Other options are incorrect: non-coding regions make up most human DNA (not limited), many have regulatory functions (not no function), they are spread across chromosomes (not segregated on a few), and their variability enables STR analysis (not too similar).

Answer:

C. can be used to uniquely identify individuals.
