Question

review: which of the following monomers are repeatedly joined together to form a strand of dna?
amino acids
nucleotides
fatty acids
polysaccharides

Explanation:

To determine the monomer of DNA, we analyze each option:

• Amino acids are monomers of proteins, not DNA.
• Nucleotides are the repeating units (monomers) that form DNA strands through polymerization.
• Fatty acids are components of lipids, not DNA.
• Polysaccharides are polymers of sugars, unrelated to DNA structure.

Answer:

nucleotides (the option labeled "nucleotides")
