DNA Test Prep

DNA is found in the cytoplasm of the cell

• True
• False

A gene is a portion of DNA that holds the code for building a protein.

• True
• False

A protein is a molecule made by ribosomes being linked together that form a specific function for an organism.

• True

• False

Answer explanation

The statement is false because proteins are made of amino acids linked together by peptide bonds, not directly by ribosomes. Ribosomes facilitate the process of translation, which synthesizes proteins from mRNA.

A codon is a 4 nucleotide segment of mRNA that carries the message for a specific amino acid

• True
• False
