Answer:
Negative to positive electrode
Since DNA is a negatively charged macromolecule.
Explanation:
DNA is a polymer of nucleotide each of which has a phosphate residue, a pentose sugar, and a nitrogenous base. The presence of phosphate residue in the DNA backbone imparts the whole DNA molecule a negative charge.
Since DNA is negatively charged, various DNA fragments are loaded at the negative terminal during the gel electrophoresis to allow their movement towards the positive electrode present at the other extreme end.
A week is the correct answer
Because they can usually predict mostly accurately up to 5-7 days which matches the answer for one week.
