Due to the semi solid or solid ground substance that accumulates in the matrix
DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode.
Answer:
With a compromised immune system, people have a far more difficult time fighting off disease. Due to this, their bodies are more vulnerable to getting such diseases and cannot create the antibodies needed to fight the disease off.
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.

Answer: A
Explanation: It makes the most sense because it isn't directly speaking about something, it is mainly summarizing the main idea. I'm not 100%, but that's the one I would choose if it were me. Hope I helped out a little!
