where is extranuclear dna located in plant cells?
in organelles
Na

mitochondria are organelles which function to transform energy as a result of cellular respiration. chloroplasts are organelles which function to produce sugars via photosynthesis in plants and algae. the genes located in mitochondria and chloroplasts are very important for proper cellular function, yet the genomes replicate independently of the dna located in the nucleus, which is typically arranged in chromosomes that only replicate one time preceding cellular division. the extranuclear genomes of mitochondria and chloroplasts however replicate independently of cell division. they replicate in response to a cell's increasing energy needs which adjust during that cell's lifespan. since they replicate independently, genomic recombination of these genomes is rarely found in offspring, contrary to nuclear genomes in which recombination is common.
