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.

Answer:
The foxes would have brown fur all year long.
Explanation:
The foxes would have brown fur all year because the change in the environment will not occur. If the change not occur in the climatic conditions, then the foxes did not change the colour of the fur so the brown colour remains for all year long. The colour of fur changes when the change in climate occurs so if there is no change in the climate so change occur in fur colour of foxes.

Answer:
One strand of all the isolated DNA double helices would have C-14 labeled thymidine.
Explanation:
DNA replication is a semiconservative process which means that each newly formed DNA double helix contains one parental strand and one newly formed strand.
Since the medium has thymidine labeled with C-14, all the newly formed strands formed during DNA replication would have radio-labeled thymidine.
Therefore, by the end of 20 minutes, one out of two strands on each double helix would have labeled thymidine nucleotides.
