Which of these contains a monosaccharide as part of its structure?
1. nucleotides, amino acids, and carbohydrates
2. carbohydrates nucleotides and
3. carbohydrates amino acids nucleotides

Explanation:

1. Nucleotides; Nucleic acids is the genetic material and it is composed of nucleotides, Nucleic acids are polymers of individual nucleotide monomers. In nucleotides two sugars: ribose and deoxyribose are found. Nucleotides are the building blocks of both RNA( ribose) and DNA (deoxyribose ). All nucleotide molecules are composed of 3 parts:

i) a 5-carbon sugar,

ii) a phosphate group and

) a nitrogenous base.

2. Carbohydrates : carbohydrates, are molecules that have carbon, hydrogen and oxygen atoms ( C₆H₁₂O₆)ₙ. Glucose monosaccharide molecules joined together to form polysaccharide.
