which discovery supported the endosymbiotic theory?\ndna in mitochondria\ndna in the cell nucleus\ndna in ribosomes\ndna in the cytoplasm
Answer
Brief Explanations:
The endosymbiotic theory proposes that mitochondria and chloroplasts were once free - living prokaryotes that were engulfed by a larger cell. The presence of DNA in mitochondria supports this as it suggests they were once independent organisms. DNA in the cell nucleus is normal for eukaryotic cells and not specific to the endosymbiotic theory. Ribosomes do not have DNA. DNA in the cytoplasm is not a key support for the endosymbiotic theory like mitochondrial DNA.
Answer:
DNA in mitochondria
