Inside the nucleus, chromatin (DNA wrapped around …
WebIf the mitochondria (or chloroplasts) are removed from a eukaryotic cell, the cell has no way to produce new ones. In other words, the “instructions” to make new mitochondria/chloroplasts is not present in the eukaryotic nuclear genome; they are present in the mitochondria/chloroplast genomes. WebThe current theory is that chloroplasts are descendants of symbiotic cyanobacteria that lived within eukaryotic cells. If we look at their respective genomes, however, we see that the cyanobacteria have many more genes than do chloroplasts. Where did these genes go? Many of them were transported to the nucleus, and others were lost.
