5. Where in the cell is the information from the mRNA strand translated into a polypeptide chain?

A. The ribosomes

6. Why is gene regulation and expression important to all living organisms?

D. All of the above

The translation of mRNA into a polypeptide chain occurs in the ribosomes. The mRNA is transported to the ribosomes, where it is read by transfer RNAs (tRNA) and translated into a sequence of amino acids that make up a polypeptide chain.

Gene regulation and expression are important to all living organisms for multiple reasons. Specific signals trigger specific genes to be transcribed and translated, leading to the production of proteins that determine most of the organism's traits. Additionally, different phases of the life cycle require specific genes for growth and development, making gene regulation and expression crucial for the survival and reproduction of the organism.
