which is composed of amino acids and determines all the structures and functions of organisms?\n○ dna\n○ ribosome\n○ mrna\n○ protein

Answer

Answer:

D. protein

Brief Explanations:

  • DNA is made of nucleotides, not amino acids.
  • Ribosomes are organelles (composed of RNA and protein) that synthesize proteins, not made of amino acids as the main component determining all organism structures/functions.
  • mRNA is a type of RNA (nucleotide - based) that carries genetic info for protein synthesis.
  • Proteins are polymers of amino acids and are responsible for most of the structures and functions in organisms (e.g., enzymes, structural components like collagen, transport proteins, etc.).
