What is the term used to describe the process by which a polypeptide chain attains its functional, three-dimensional structure?

• a) Transcription
  

• b) Translation
  

• c) Protein Folding

What determines the final three-dimensional structure of a protein?

• Number of hydrogen bonds formed
• Amino acid sequence and interactions between the amino acids
• Temperature at which the protein is stored
• The color of the protein

What determines the primary structure of a protein?

• Sequence of amino acids and The DNA sequence of the gene coding for the protein

• Temperature of the environment
• Number of hydrogen bonds
• Size of the protein

Why is the primary structure of a protein important?

• The primary structure of a protein is important because it determines the protein's size
• The primary structure of a protein is important because it determines the sequence of amino acids, which in turn dictates the protein's overall structure and function.
• The primary structure of a protein is important because it affects the protein's taste
• The primary structure of a protein is important because it determines the protein's color

Joining of two amino acids is a ________ reaction because a _______ molucule is formed.

• dehydration, oxygen
• polymerization, nitrogen
• condensation, water
• hydrolysis, carbon dioxide
