Question

multiple select question
select all that apply
choose all that are directly involved in the process of protein synthesis.

☐ trna
☐ mrna
☐ mitochondria
☐ lysosomes
☐ ribosomes
☐ dna

Explanation:

• tRNA: Transfers amino acids to ribosomes during translation, directly involved in protein synthesis.
• mRNA: Carries genetic code from DNA to ribosomes, a key part of protein synthesis.
• Ribosomes: The site of translation where proteins are synthesized, directly involved.
• DNA: Contains the genetic information (genes) that code for proteins; transcription of DNA to mRNA is the first step in protein synthesis, so DNA is directly involved in providing the code.
• Mitochondria: While they have their own protein synthesis, the question is about general protein synthesis. Mitochondria are not directly involved in the main cytoplasmic protein synthesis pathway (they are organelles for energy, not the core machinery of protein synthesis for most cellular proteins).
• Lysosomes: Involved in digestion and waste removal, not protein synthesis.

Answer:

A. tRNA, B. mRNA, E. Ribosomes, F. DNA
