Analyze DNA is isolated from a hair found in a knit hat that was recovered from the scene of a bank robbery. DNA fingerprints ar
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.

<h3>DNA in the hair?</h3>

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.

Fantom [35]

Answer:

3.5 billion years ago, or in the Eoarchean Era.

Explanation:

The first known single-celled organisms appeared on Earth about 3.5 billion years ago, roughly a billion years after Earth formed. More complex forms of life took longer to evolve, with the first multicellular animals not appearing until about 600 million years ago.

The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago, during the Eoarchean Era.
