Answer
the correct answer is option (b)
Work Step by Step
Nucleic acids are formed by the combination of several nucleotides. Nucleotides are building blocks of nucleic acids. Each nucleotide contains a ribose or deoxyribose sugar, a nitrogen base, and a phosphate group. The nucleotides in a nucleic acid are joined by phosphodiester bonds, which are covalent bonds.
Step 2 of 3 A nucleotide is composed of a sugar, nitrogen – containing base, and a phosphate group. Hence, option (a) is not the correct choice. Individual nucleotides in a nucleic acid are linked by alternating covalent bonds between the sugars and phosphate groups. Hence, option (c) is not the correct choice. Both DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are two different types of nucleic acids. Each of them have defined functions. Both these forms of nucleic acids are composed of nucleic acids. Hence, option (d) is not the correct choice.
Step 3 of 3 Nucleotides are building blocks of nucleic acids. They are not found in fats and carbohydrates. Fats are made of fatty acids and other hydrophobic alkyl groups. Monosaccharides are the monomers of carbohydrates. Hence, the correct answer is option (b)
