To identify people by dna, is it better to make copies of genes or non-coding segments? Explain.
castortr0y [4]

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________molecules that are produced from DNA are used by the cell's​
Temka [501]

Answer:

The majority of genes carried in a cell's DNA specify the amino acid sequence of proteins; the RNA molecules that are copied from these genes (which ultimately direct the synthesis of proteins) are called messenger RNA (mRNA) molecules.
