Detailed explanation-1: -There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C).
Detailed explanation-2: -Guanine-cytosine base pairs, or GC base pairs, are held together by 3 hydrogen bonds. The hydrogen bond donors and acceptors are labeled on the bases. The hydrogen bond donors are all NH groups. The hydrogen bond acceptors can be either nitrogen or oxygen atoms with a lone pair of electrons.
Detailed explanation-3: -ACGT is an acronym for the four types of bases found in a DNA molecule: adenine (A), cytosine (C), guanine (G), and thymine (T). A DNA molecule consists of two strands wound around each other, with each strand held together by bonds between the bases. Adenine pairs with thymine, and cytosine pairs with guanine.
Detailed explanation-4: -An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA. Attached to each sugar is one of four bases: adenine (A), uracil (U), cytosine (C) or guanine (G).
