Genetics Trivia - Learn About Your Genes

Genetics is a branch of biology concerned with the study of genes, genetic variation, and heredity in organisms. In humans, genes vary in size from a few hundred DNA bases to more than two million bases. This is an easy peasy quiz with really simple questions about genetics. All the best!

  • 8. 
    What is true about hemoglobin

      It contains 4 alpha globin polypeptides

    • C. 

      It is found in red blood cells

      It is made up of around 600 amino acids

      It is a fatty acid

      It is a protein

      All of the above

  • 9. 
    How does the oxygen leave the hemoglobin and then the red blood cell into the body?
    • A. 

      Transformation

    • B. 

      Partial pressure

    • C. 

      Diffusion

    • D. 

      Osmosis

  • 10. 
    The reason o2 enters the red blood cell and binds to the hemoglobin protein from the lungs is because...?
    • A. 

      This occurs in the heart not the lungs!

    • B. 

      Because there is a higher concentration of o2 in the lungs and the law of partial pressure states that gasses diffuse from an area of higher partial pressure to an area of lower partial pressure (like diffusion) and the lungs have a high concentration and the RBC's have a lower concentration. Therefore the o2 enters the RBC's

    • C. 

      Because o2 is hydrophilic and areas on the red blood cell are hydrophobic, therefore the o2 is attracted to the hydrophobic areas on the red blood cell and the o2 binds to it. 

    • D. 

      O2 does not enter and bind to hemoglobin through the lungs. This occurs in the brain where complexity thrives and blood is constantly entering. 

  • 11. 
    True or false, when talking about proteins, the shape is the most important thing that dictates function
    • A. 

      True

    • B.

      R-group

  • 14.

      True

    • B. 

      False

  • 15. 
    The most common and normal reason proteins fold is because...
    • A. 

      They become denatured and they fold to nature themselves

    • B. 

      Because they always need to move to their lowest energy state 

    • C. 

      Chaperones

    • D. 

      Of a change in PH

  • 16.

    • A. 

      Hydrophobic amino acids in the middle

      Tape

    • B. 

      The partial negative forces of the oxygen attracting to the partial positive forces from the hydrogen 

    • C. 

      Enzymes

    • D. 

      Glue

  • 18. 
    Why does the amino acid sequence dictate the the shape and therefore the function of the protein. 
    • A. 

      Because each amino acid has it's own specific function, and the combos of amino acids create a chemical change causing a different function. 

    • B. 

      Because the hydrophilicity and hydrophobicity determine how the protein folds, and because of that, it determines the function of the protein

    • C. 

      They don't, the shape of the protein is created based off of specific mRNA signals. 

    • D. 

      All of the above

  • 19.
