Step 1: Concept
The central dogma of molecular biology involves the transcription of DNA to RNA and the translation of RNA into proteins.
Step 2: Meaning
Protein synthesis is the biological process by which individual amino acids are connected in a specific sequence to form polypeptide chains.
Step 3: Analysis
While lysosomes digest materials and mitochondria produce ATP, ribosomes serve as the actual site for translating genetic code into proteins. They are found either floating in the cytoplasm or attached to the endoplasmic reticulum.
Step 4: Conclusion
Ribozomes are the specialized cellular machinery dedicated to the assembly of proteins.
Final Answer: (D)
