Question

1. choose the correct sequence of terms to fill in this sentence correctly:

____ are the monomers of __, which code for the next __ in a sequence that makes up ____.

• nucleotides, dna molecules, amino acid, a protein
• proteins, amino acids, dna molecule, a nucleotide
• dna molecules, nucleotides, protein, an amino acid
• amino acids, proteins, nucleotide, a dna molecule

Explanation:

To solve this, we analyze the biological relationships:

• Monomers of DNA are nucleotides (so DNA is a polymer of nucleotides).
• DNA codes for proteins via transcription and translation, where DNA's nucleotide sequence codes for amino acid sequences (proteins are polymers of amino acids).
• Let's check each option:
• Option 1: Nucleotides (monomers) → DNA (polymer), DNA codes for amino acids (which make proteins). This fits: Nucleotides are monomers of DNA molecules, DNA codes for amino acid (sequence) to make a protein.
• Option 2: Proteins are polymers (not monomers) of amino acids; DNA doesn't code for nucleotides in this context. Incorrect.
• Option 3: DNA is a polymer (not monomer) of nucleotides. Incorrect.
• Option 4: Amino acids are monomers of proteins, but proteins don't code for nucleotides (DNA/RNA code for amino acids). Incorrect.

Answer:

A. Nucleotides, DNA molecules, amino acid, a protein
