Answer:

D. The DNA in B is more positively charged than the DNA in A.​

D. The DNA in B is more positively charged than the DNA in A.​

Explanation:

The DNA in band B is relatively smaller than that of the DNA in band A.  Option A is correct.

DNA Electrophoresis:

  • It is a technique that is used to separate DNA fragments of different sizes.
  • In this technique, agarose gel is used as the base.
  • DNA moves from the negative electrode towards the positive electrode.
  • Large DNA molecules run slower than smaller DNA molecules because small molecules easily pass through the pores of the agarose gel.

Therefore, the DNA in band B is relatively smaller than that of the DNA in band A.
