Question

multiple choice question what is true about the dna found in the eukaryotic organelles that were derived from the endosymbiosis of proteobacteria and cyanobacteria? the dna contains all the genes necessary for the organelles to live outside their hosts cells the dna in the organelles retains all of its original genes. many genes have moved to the nuclei of the host cells. the dna has complexed with rna to form a hybridized type of nucleic acid

Explanation:

According to the endosymbiotic theory, mitochondria (derived from proteobacteria) and chloroplasts (derived from cyanobacteria) were once free - living prokaryotes. Over time, during the process of endosymbiosis, many of their genes have migrated to the nucleus of the host eukaryotic cell. The organelles' DNA does not contain all genes for independent living outside the host, nor does it retain all original genes, and there is no common process of DNA - RNA complexing to form a hybridized nucleic acid in this context.

Answer:

O Many genes have moved to the nuclei of the host cells.
