Answer:
Adenine binds to guanine.
Explanation:
Rules of the base pairing are:
A with T
Purine base, adenine (A) pairs with the pyrimidine base, thymine (T).
C with G
Pyrimidine base, cytosine (C) pairs with purine base, guanine (G).
<u>(Option A is correct).
</u>
<u>(Option B is incorrect).
</u>
Nitrogenous bases are positioned in the inside helix structure like the rungs of a staircase due to hydrophobic effect and are stabilized by hydrogen bonding.
<u>(Option C and D is correct).

Answer:
When helicase mutations occur, problems in DNA replication are found. The helicases are proteins that open the 2 strands of DNA to initiate the duplication, they are responsible for breaking the hydrogen bonds between the two DNA chains, thus separating the chains, also they have the function of repairing DNA mutations, if there is mutation in the gene that encodes them, various functions will be absent in the cell.
