The key difference in protein synthesis between prokaryotes and eukaryotes is that prokaryotes can transcribe and translate proteins simultaneously, while eukaryotes separate these processes both in time and location. This leads to differences in how gene expression is regulated in these two types of organisms. Thus, the correct answer to the question is option D. ;
The main difference between protein synthesis in prokaryotes and eukaryotes is that prokaryotes can carry out transcription and translation simultaneously, while in eukaryotes these processes are separated. Both types of cells synthesize mRNA from DNA, use ribosomes for protein synthesis, and require energy to do so. Thus, the correct answer is option D.
