1 细胞膜亚显微结构图内侧的紫色丝状物是什么?细胞膜内表面与细胞质中的微管和微丝的网架相联系,这些微管和微丝的活动对细胞膜和其中的蛋白质的移动有一定的影响,因此紫色丝状物应是组成细胞骨架的一些纤维,而这些纤维是由蛋白质构成的,紫色丝状物实质上就是丝状蛋白。2 原核细胞的核 DNA 是环状还是丝状?高中生物必修教材第一册 P.33在描述原核细胞的亚显微结构时
1 What is the purple filament inside the subcellular structure of the cell membrane? The inner surface of the cell membrane is linked to the network of microtubules and microfilaments in the cytoplasm. The movement of these microtubules and microfilaments on the cell membrane and the movement of the proteins therein Have a certain impact, purple filaments should be composed of some of the cytoskeleton fibers, and these fibers are made of protein, purple filament is essentially a filamentous protein. 2 prokaryotic nuclear DNA is circular or filamentous? High school biology compulsory textbook first P.33 in describing the sub-microscopic structure of prokaryotes
