115 hydrogen bonds will be involved in base pairing in a DNA molecule of 50 bp that contain 15 cytosine bases.
According Chargaff's rule, guanine (G) binds to cytosine (C) with 3 hydrogen bonds, while adenine (A) binds to thymine (T) with 2 hydrogen bonds.
So, the given DNA molecule (50bp) has 15 cytosine bases, i.e. 15 G-C pairing (15 x 3 = 45 hydrogen bonds) & 35 A-T pairing (35 x 2 = 70 hydrogen bonds).
45 + 70 = 115 hydrogen bonds.

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...
