Question

1. in an eye cell, which of the following gene sections would be transcribed?

a. the eye switch
b. the arm switch
c. the protein x coding region
d. a and c
e. all of the above

1. in an eye cell, which of the following proteins would be present?

a. an activator for the eye switch
b. an activator for the arm switch
c. protein x
d. both a and c
e. all of the above

Explanation:

In an eye cell, the eye - specific regulatory elements (like the eye switch) and the coding regions related to eye - specific functions (such as the protein X coding region if it is eye - relevant) are transcribed. The arm switch is not relevant to an eye cell. For the proteins, an activator for the eye switch (to turn on eye - specific genes) and Protein X (if it is produced from the transcribed coding region) would be present. An activator for the arm switch is not relevant to an eye cell.

Answer:

1. d. A and C
2. d. Both A and C
