Question

proteins play a vital role in all cells. in fact, cells need thousands of proteins in order to function properly. what primarily directs the synthesis of proteins?
a. the energy that is stored in mitochondria
b. the folding patterns of strands of rna
c. the cytoplasm found throughout a cell
d. the genetic information stored in dna

Explanation:

Proteins are synthesized based on the genetic information stored in DNA. DNA contains the instructions for making proteins. RNA is involved in the process of translating this genetic information into proteins, but it's the DNA - stored genetic information that primarily directs protein synthesis. Mitochondria are related to energy - production (ATP synthesis) and not protein synthesis. Cytoplasm is the site where some protein - synthesis steps occur, but it doesn't direct the process.

Answer:

D. the genetic information stored in DNA
