A couple who is having genetic counseling asks the nurse about the nucleolus of the cell. Based on this information, what is the best explanation of the function of the nucleolus?
A) Carries inherited characteristics
B) Helps in the formation of genes
C) Helps in the formation of ribosomes
D) Transports materials across cells
C
Feedback:
The function of the nucleolus is to form ribosomes. Forming genes is the function of the chromosomes, and genes carry information about inherited characteristics. The cell membrane, or plasma membrane, as a result of its semipermeability, helps in transporting materials across cells; the nucleolus does not do this.
