Question

name: directions: circle the letter of the correct answer. each question is worth 1 point. block: date: multiple choice test - nucleic acids 1. what is the building block (monomer) of nucleic acids? a. amino acid b. monosaccharide c. nucleotide d. fatty acid 2. which of the following is not part of a nucleotide? a. phosphate group b. sugar c. nitrogen base d. amino group 3. which nucleic acid stores hereditary information? a. protein b. rna c. dna d. lipid

Explanation:

1. Nucleic acids are polymers made of nucleotides. Amino acids are the building - blocks of proteins, not nucleic acids.
2. A nucleotide consists of a phosphate group, a sugar, and a nitrogen - base. An amino group is not part of a nucleotide.
3. DNA (deoxyribonucleic acid) stores hereditary information. RNA can also carry information but DNA is the main molecule for storing hereditary info in most organisms, and proteins and lipids do not store hereditary information in the same way.

Answer:

1. C. Nucleotide
2. D. Amino group
3. C. DNA
