线粒体是细胞能量产生的重要结构。可能是具有呼吸能力的较小细胞被寄生细胞吞噬后,长期共生演变而来。所以线粒体可能有它们自己的遗传物质和表达这些物质的机构。早在40年前,人们就已注意到了线粒体可能具有自己的基因,而且这些基因与核基因不同。但 Mitochondria are important structures of cellular energy production. It may be that the smaller cells with respiratory capacity are phagocytosed by parasitic cells and evolved from long-term symbiosis. Therefore, mitochondria may have their own genetic material and the mechanism of expressing these substances. As early as 40 years ago, people have noticed that mitochondria may have their own genes, and these genes and nuclear genes are different. but
