Final answer:
Nucleotides form the polynucleotides found in DNA and RNA and do not directly create proteins or fats. The monomers comprising nucleotides are the sugar molecule, a phosphate group, and a nitrogenous base, essential for the structure and function of DNA and RNA.
Step-by-step explanation:
Nucleotides hook together to form both DNA and RNA, not proteins or fats. The correct answer to the question is (c) DNA and RNA. Each nucleotide consists of three main components: a pentose (five-carbon) sugar, a phosphate group, and a nitrogenous base. These components combine to create the structure of DNA and RNA; however, they do not directly form proteins or fats.
DNA is formed from nucleotides that bond to create a double helix structure, using the sugar and phosphate as a backbone and the nitrogenous bases to form complementary base pairs through hydrogen bonding. RNA, similar to DNA, is also made up of nucleotides, forming a single-stranded molecule that plays a crucial role in protein synthesis. Unlike nucleotides, proteins are made up of amino acids, and fats are composed of fatty acids and glycerol.
