Question 8

With both bacterial and eukaryotic cells constantly dying and breaking down around us, and with a tremendous load of fragmentary DNA washing around in the fluid world, why aren't genes being transferred among various living organisms at a massive scale daily?

Accepted Answer

A)   DNA that is not protected inside a protein coat or membrane is very vulnerable.
B)   Living cells maintain a very effective barrier to the introduction of large molecules.
C)   Since a vector appears necessary to snatch up DNA from one protected source and inject it into a cell, "naked" DNA is apparently vulnerable and unable to cross membranes easily.
D)   All of the choices are correct.

G) A) and B)

Question 9

Accepted Answer

A)   Progress in determining the function of DNA sequences, making comparisons between our genome and other model organisms, and understanding how genes and proteins interact with cells would stop.
B)   Many cures for genetic disorders would not be discovered.
C)   The creation of new transgenic plants, animals and bacteria that benefit society would not occur.
D)   All of these are consequences if the field of bioinformatics ceased to exist as a field of study.E) C) and D)
F) B) and D)

Question 10

F) All of the above

Question 11

Which of the following health disorders can be treated with ex vivo gene therapy?

Accepted Answer

A)   Liver cells lack a protein that enables it to remove cholesterol from the blood which leads to high levels of cholesterol in the blood. This can increase the patients susceptibility to heart attacks.
B)   The liver cells lack a protein that causes it to produce excessive cholesterol which leads to high levels of cholesterol in the blood. This can increase the patients susceptibility to heart attacks.
C)   A gene is implanted that will code for the correct transmembrane carrier of the chloride ion.
D)   Genes are implanted that make healthy cells more tolerant to chemotherapy while making the tumor cells more susceptible to chemotherapy.E) All of the above
F) None of the above
