weak hydrogen bonds between the bases

Detailed explanation-1: -Hydrogen bonds occur between the two strands and involve a base from one strand with a base from the second in complementary pairing. These hydrogen bonds are individually weak but collectively quite strong. a template during DNA replication.
Detailed explanation-2: -Base Pair The two strands are held together by hydrogen bonds between pairs of bases: adenine pairs with thymine, and cytosine pairs with guanine.
Detailed explanation-3: -The answer is B: hydrogen bonds are easier to break allowing for DNA copying. Hydrogen bonds formed between complementary base pairs on opposite DNA strands form the “rungs on a ladder” portion of DNA’s double-helical structure.
Detailed explanation-4: -DNA is made up of a double-stranded helix held together by weak hydrogen bonds between purine-pyrimidine nucleotide base pairs: adenine (A) paired with thymine (T), and guanine (G) paired with cytosine (C).
