In 1st ion, negative charge is on Oxygen atom
In 2nd ion, negative charge is on Nitrogen atom
The more electronegative the atom, greater is electron holding capacity and hence electron donating tendency is less and hence that will be a weaker base.
Oxygen is more electronegative that Nitrogen and because of this the ion with negative charge on Oxygen is weaker base.

Question 1 1 pts Why is it important for DNA to have complementary base pairing? O Complementary base pairing allows base pairs to be packed in the most energetically favorable arrangement inside of the double helix structure. O Complementary base pairing will pair a purine with a purine, which are a similar width, thus they are able to hold the sugar-phosphate backbone an equal distance apart along the DNA molecule o Complementary base pairing is only important for maintaining the...
