What would happen if the bases in DNA strands were connected by a bond other than a hydrogen bond?
tekilochka [14]
The correct answer is It would be more difficult for DNA to unzip since it would require more energy to break the bonds.

That is because it would most probably be a covalent bond and such a bond is stronger than a hydrogen bond which means that more energy would be needed to break it.

If a double-stranded segment of DNA has been found to have 23 purines and 15 thymines, how many guanines are there?
Serggg [28]

Answer: 4 Guanines

Explanation: Following Chargaff's ratio that describes the ration of purines to pyrimidines as 1:1, if there are 23 purines, it follows that there should be 23 pyrimidines; 15 Thymines should therefore be hydrogen bonded to 15 Adenines by complementary base pairing.

We are then left with 8 nucleotides composed of guanines and cytosines in complementary base pairs. This means that half that number (4) should be guanines and the rest cytosines.
