a A bacterial cell contains thousands of ribosomes which are made of RNA and protein. When viewed even by very high magnification, ribosomes show up as fine, spherical specks dispersed throughout the cytoplasm that often occur in chains (polysomes). 一个细菌细胞包含由RNA和蛋白质制成的数以...

A eukaryotic cell (left) has membrane-enclosed DNA, which forms a structure called the nucleus (located at center of the eukaryotic cell; note the purple DNA enclosed in the pink nucleus). A typical eukaryotic cell also has additional membrane-bound organelles of varying shapes and sizes. In ...
In addition to the three classical protein secretion pathways mentioned above, researchers also found that many non-classical secretion pathways are used to secrete non-classical proteins lacking any known signal peptides or secretion motifs [41]. Wang et al. used four typical non-classical secretory...

Flagella, the helical propellers that extend from the bacterial surface, are a paradigm for how complex molecular machines can be built outside the living cell. Their assembly requires ordered export of thousands of structural subunits across the cell membrane and this is achieved by a type III ...
A typical unit has a waste feeding system; chamber of waste processing; solid residues handing system, which also helps remove solid waste; synthesis gas management system; and monitoring and control [25]. The process flow can be depicted in Fig. 7. Fig. 7 Plasma gasification process flow ...
1d. We fitted a Bézier curve through the centroids of the outermost cells, and measured the angle ψ between the curve and each boundary cell. For a typical colony just before it buckled, most peripheral cells show ψ ≲ 30°, Fig. 3a. Such ‘active anchoring’ is also seen in ...
Cell ghosts featuring the typical C. crescentus morphology and numerous smaller vibrioid B. exovorus cells were visible after overnight co-incubation of both species, indicating predation (Fig. 1a). Beside C. crescentus, no other α-proteobacterium was described as prey for B. exovorus. Here...
