zepelin [54]

The DNA of the samples is isolated, and then the mapping is carried out, which is done by equipment called "DNA Sequencers". With this, it is possible to compare the genomes and conclude to whom the hair belongs.

In the case of hair, researchers can rely on these two types of DNA (nuclear and mitochondrial). However, according to the Easy-DNA Laboratory, a hair that is cut, unfortunately, does not contain any valid DNA nucleus. However, when the hair still contains the hair bulb (hair root) it is possible to extract the nuclear DNA, because in that region we have thousands of hair forming cells (keratinocytes).

With this information, we can conclude that the DNA can be analyzed and compared, arriving at who committed the bank robbery.
