Organelles and Nucleic Acid Presence

Steps:

• Nucleic acids are DNA and RNA, found in organelles involved in genetic or protein synthesis.
• Chloroplasts contain their own circular DNA for photosynthesis genes.
• Mitochondria have mitochondrial DNA encoding some proteins.
• Ribosomes consist of rRNA and proteins for translation.
• Golgi bodies process and package proteins without DNA or RNA.

Why B is correct:

• Golgi bodies are stacks of membranous sacs that modify lipids and proteins but lack nucleic acids, per cell biology definitions of organelle composition.

Why the others are wrong:

• A: Chloroplasts house cpDNA, a type of nucleic acid for organelle function.
• C: Mitochondria contain mtDNA, essential for energy production.
• D: Ribosomes include rRNA, a nucleic acid component for protein assembly.

Final answer: B
