Detailed explanation-1: -Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases–adenine (A), cytosine (C), guanine (G), or thymine (T).
Detailed explanation-2: -Answer and Explanation: The sides of DNA are made up of deoxyribose sugar molecules and phosphate molecules.
Detailed explanation-3: -A free, unincorporated nucleotide usually exists in a triphosphate form; that is, it contains a chain of three phosphates. In DNA, however, it loses two of these phosphate groups, so that only one phosphate is incorporated into a strand of DNA.
Detailed explanation-4: -Molecular Biology and Genetic Engineering DNA has three main components: the phosphate (PO4) groups, five-carbon sugars, and nitrogen-containing bases calledpurines, comprising adenine (A) and guanine (G), andpyrimidines, comprising thymine (T) and cytosine (C). These basic subunits are callednucleotides.
Detailed explanation-5: -Answer and Explanation: The sides of the DNA ladder are made of sugar-phosphate groups. The sides are also known as the backbone, and they help form the structure of the DNA, which is a double helix. A double helix is similar to taking a ladder and twisting it around in a spiral.
