Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The final product of protein synthesis is a protein. Proteins are made up of polypeptide chains, which are chains of amino acids.

Multiple choice

  2. Rituximab

  3. Trastuzumab

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Adalimumab, Rituximab, and Trastuzumab are all examples of monoclonal antibodies produced using Industrial Biotechnology through hybridoma technology or recombinant DNA technology.

Multiple choice

Which of the following is NOT a type of protein structure?

  1. Primary structure

  2. Secondary structure

  3. Tertiary structure

  4. Quaternary structure
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Quaternary structure is a type of protein-protein interaction, not a type of protein structure.

Multiple choice

  1. Phosphorylation

  2. Glycosylation

  3. Acetylation

  4. Methylation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Acetylation is a type of protein modification, not a post-translational modification.

Multiple choice

Which of the following is NOT a type of protein kinase?

  1. Receptor tyrosine kinase

  2. Non-receptor tyrosine kinase

  3. Serine/threonine kinase

  4. Lipid kinase
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Lipid kinases are a type of enzyme, not a protein kinase.

Multiple choice

Which of the following is NOT a key component of systems biology?

  1. Genomics

  2. Proteomics

  3. Metabolomics

  4. Thermodynamics
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Thermodynamics is not a core component of systems biology, which focuses on understanding the interactions and dynamics of biological systems at the molecular and cellular levels.
