Detailed explanation-1: -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.
Detailed explanation-2: -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-3: -The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base (Figure 9.3).
Detailed explanation-4: -Step 1: Locate the sugar at the center of the nucleotide. Step 2: Locate the phosphate groups attached to the 5’ carbon. Step 3: Once the sugar and phosphate groups are identified, the remaining branch provides the identity.
