Which of the following organelles does not have DNA?

✅Explanation:
-Lysosome: These are membrane-bound organelles responsible for breaking down cellular waste and foreign materials. They contain powerful enzymes but no DNA.
-Chloroplast: Found in plant cells, chloroplasts contain their own DNA (chloroplast genome) separate from the nuclear DNA. This DNA codes for proteins involved in photosynthesis.
-Nucleus: The central organelle of the cell, housing the main genetic material (chromosomes) in the form of DNA.
-Mitochondria: These "powerhouses" of the cell have their own DNA (mitochondrial genome) that encodes proteins for energy production.

🔴Related Terminologies::
-Genome: The complete set of genetic material present in an organism.
-Organelle genome: DNA molecules found within specific organelles like mitochondria and chloroplasts.
-Endosymbiotic theory: Proposes that mitochondria and chloroplasts originated from bacteria that were engulfed by other cells and formed a symbiotic relationship.
