Give two reasons why dna evidence analysis is an imperfect science

Biology
1 answer:
Virty [35]3 years ago
7 0

Answer:

DNA samples might be planted and it is possible to synthesize a nucleotide sequence to incriminate a person

Explanation:

In a criminal case, DNA evidence may be considered to be fraudulent because DNA samples might be planted around the crime scene. Moreover, specific genomic profiles of an individual stored in the database can be used to manufacture a DNA sample matching this profile without the necessity to obtain tissues of the person. In consequence, DNA evidence may be considered to be imperfect. Nonetheless, it is important to highlight that DNA evidence is one of the most important modern advances used during criminal trials, and it has proven to be a very useful (and effective) tool available in law enforcement.

In the currently accepted atomic model, an electron orbits the nucleus in a<br> clear, defined path.
Alex777 [14]

FALSE

In the currently accepted atomic model, an electron orbits around the nucleus is NOT in a clear, defined path.

Explanation:

According to modern atomic models, like the Bohr theory, it is difficult to know the exact location and path of an electron around the nucleus. This is partly because the mere act of observing the electrons changes its position. This is because the electrons have negligible mass and therefore ‘hitting’ them with any form of radiation for ‘illumination’ changes its position, behavior, and properties. In addition, the movement of electrons is very rapid such that by the time one observes the instantaneous location of an electron, if it was possible, it will have changed its position.

Therefore modern theories, such as VSPER, model atoms based on properties of where an electron will highly likely be found. This is how the shells and subshells of electrons (s, p, d, f) are modeled.
