While both DNA fingerprinting and traditional fingerprinting are useful forensic tools, DNA profiling is generally considered more reliable and definitive than traditional fingerprinting, which can be subject to human interpretation and error. Additionally, the processes and technologies involved in DNA analysis can be more complex than those for traditional fingerprints.

The correct response is: a person's DNA profile is unique to only that person and found in every cell of the body, some of which are often found at the scene of the crime.
This uniqueness and the presence of DNA in various biological samples (like blood, hair, skin cells) make DNA profiling a powerful tool for identifying individuals involved in criminal cases.

Which of the following answers shows the appropriate organizational order from smallest to largest? In other words, the first structure is a component of the following, the second structure a component of the third, and so on.
Responses
DNA molecule, chromosome, cell, paired bases, gene, arm, person

chromosome, DNA molecule, paired bases, gene, cell, arm, person
chromosome, DNA molecule, paired bases, gene, cell, arm, person
paired bases, DNA molecule, chromosome, gene, cell, arm, person
The correct response is: paired bases, DNA molecule, gene, chromosome, cell, arm, person.
This order accurately reflects the hierarchical structure, where paired bases are components of DNA molecules, which in turn compose genes, which are part of chromosomes, which are found in cells, and so on up to a person. Note, however, that "arm" typically refers to a part of a chromosome, so it doesn't fit well into the hierarchical structure of DNA.
