Question

nucleic acids are molecules that contain carbon, hydrogen, oxygen, nitrogen, and phosphorus. there are two types of nucleic acids: dna (deoxyribonucleic acid) and rna (ribonucleic acid). nucleic acids are polymers that are made of monomers called nucleotides. a nucleotide is comprised of 3 parts: a sugar, a phosphate group, and a nitrogenous base. nucleic acids contain the instruction to build proteins.
nucleic acids are different from the other macromolecules discussed. carbohydrates, lipids, and proteins have many different functions, whereas nucleic acids only have one - to code for proteins.

match each term with its appropriate definition.

1. ______monomer a. the bond that holds amino acids together
2. ______polymer b. a smaller part of a larger molecule; subunit
3. ______carbohydrate c. made of dna and rna
4. ______fatty acid d. a large molecule comprised of smaller monomers
5. ______protein e. the monomer of a nucleic acid
6. ______amino acid f. made of c, h, and o and includes starches and sugars
7. ______lipid g. made of c, h, and o and includes waxes, oils, and cholesterol.
8. ______nucleotide h. molecules that contain c, h, o, and n
9. ______nucleic acid i. a polymer that is comprised of amino acids
10. ______peptide bond j. chains of carbon atoms bonded to hydrogen atoms (found in lipids)

Explanation:

• Monomer: A monomer is a smaller part of a larger molecule; subunit. This matches option b.
• Polymer: A polymer is a large molecule comprised of smaller monomers. This matches option d.
• Carbohydrate: Carbohydrates are made of C, H, and O and include starches and sugars. This matches option f.
• Fatty acid: Fatty acids are chains of carbon atoms bonded to hydrogen atoms (found in lipids). This matches option j.
• Protein: Proteins are polymers that are comprised of amino acids. This matches option i.
• Amino acid: Amino acids are molecules that contain C, H, O, and N. This matches option h.
• Lipid: Lipids are made of C, H, and O and include waxes, oils, and cholesterol. This matches option g.
• Nucleotide: A nucleotide is the monomer of a nucleic acid. This matches option e.
• Nucleic acid: Nucleic acids are made of DNA and RNA. This matches option c.
• Peptide bond: The peptide bond is the bond that holds amino acids together. This matches option a.
