BIOMOLECULES AND ENZYMES

Detailed explanation-1: -C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)

Detailed explanation-2: -Chargaff’s rule, also known as the complementary base pairing rule, states that DNA base pairs are always adenine with thymine (A-T) and cytosine with guanine (C-G).

Detailed explanation-3: -In DNA, adenine always pairs with thymine (A-T), and guanine always pairs with cytosine (G-C).

Detailed explanation-4: -DNA and RNA bases are also held together by chemical bonds and have specific base pairing rules. In DNA/RNA base pairing, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G).

Detailed explanation-5: -The Adenine-Thymine base pair is held together by 2 hydrogen bonds while the Guanine-Cytosine base pair is held together by 3 hydrogen bonds. That is also the reason why the two strands of a DNA molecule can be separated more easily at sections that are densely populated by A-T base pairs.
