BIOMOLECULES AND ENZYMES

Detailed explanation-1: -A nucleotide is a subunit of DNA or RNA that consists of a nitrogenous base (A, G, T, or C in DNA; A, G, U, or C in RNA), a phosphate molecule, and a sugar molecule (deoxyribose in DNA, and ribose in RNA). Adenine (A) is one member of the A-T (adenine-thymine) base pair in DNA.

Detailed explanation-2: -A molecule consisting of a nitrogen-containing base (adenine, guanine, thymine, or cytosine in DNA; adenine, guanine, uracil, or cytosine in RNA), a phosphate group, and a sugar (deoxyribose in DNA; ribose in RNA).

Detailed explanation-3: -Figure 3.14. 1: RNA Structure: A nucleotide is made up of three components: a nitrogenous base, a pentose sugar, and one or more phosphate groups.

Detailed explanation-4: -All of the information needed to build and maintain an organism-whether it’s a human, a dog, or a bacterial cell-is contained in its DNA. DNA molecules are composed of four nucleotides, and these nucleotides are linked together much like the words in a sentence.
