Answer:
Vacina ( eu estou aprendendo sobre isso na minha aula, e acho que seria legal por que é uma coisa muito discutida atualmente)
The two types are, aerobic where the final electron acceptor of the Electron Transport Chain is oxygen, and anaerobic, where the final electron acceptor of the Electron Transport Chain is a molecule aside from oxygen.
DNA samples are added into wells with the help of electric current.
<h3>How dna samples added to the wells?</h3>
DNA samples are added into wells at one end of a gel whereas an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
So we can conclude that DNA samples are added into wells with the help of electric current.
