Question 20 (2 points)
Which of the following best describes the relationship between a mutation and a resulting change in the eye color of a rabbit?

Question 20 options:

gene structure changes --> protein function changes --> protein structure changes --> observable trait changes

protein structure changes --> protein function changes --> gene structure changes --> observable trait changes

Question 21 (2 points)
Which of the following best describes what happens in genetic medicine using CRISPR technology?

Question 21 options:

The DNA sequence of the gene is edited using a guide DNA and Cas9. The DNA can be cut and deleted or new DNA can be inserted.

DNA is inserted into a virus and then put into a person. The virus "infects" the patient with the "good" DNA.

Proteins are inserted into a patient to kill off mutated DNA

Healthy proteins are inserted into a patient since their DNA does not produce the right proteins.

Question 23 (2 points)
Which of the following best describes how genetic research targeting DNA affects proteins.

Question 23 options:

Since DNA gets it's code from mRNA, targeting the DNA does not really change the original code or the proteins created in the body.

The DNA code can change, but since DNA changes to mRNA first it will not affect the protein function in our bodies.

Proteins create the DNA code, so by changing the proteins we change the DNA. DNA won't change the proteins created.

Since DNA is the original code the body uses to make proteins, changing the DNA will ultimately affect the proteins being formed and working in our bodies.
