| 1. | After adherence, the particle is enveloped by cell membrane .
附着之后，粒子被细胞膜包裹。 |
| 2. | The envelope is derived in most cases from the cytoplasmic membrane .
大多数病毒的囊膜取自宿主细胞膜。 |
| 3. | These materials are virtually absent from other cytomembranes .
这些物质在其它的细胞膜中实际上是不存在的。 |
| 4. | Unlike animal cell membranes, plant membranes do not contain cholesterol .
与动物细胞膜不一样，植物的膜不含胆固醇。 |
| 5. | Adherence of the particle to the cell membrane is the first step in the process .
粒子附着到细胞膜上是这个过程的第一步。 |
| 6. | Rather, a broad variety of proteins seem to exist in different cell membranes .
当然，不同的细胞膜中存在着多种多样蛋白质。 |
| 7. | When the tip penetrates the cell membrane, the membrane seals around the glass capillary .
当尖端穿透细胞膜，膜即将玻璃毛细管封住。 |
| 8. | Such extraction modifies the whole cell-membrance network throughout the wool fiber .
这种萃取改变了整个毛纤维中所有细胞膜的网状结构。 |
| 9. | In advanced stages of shock, the outer cell membrane often breaks up and the cell dies .
在休克的进展阶段，最外面的细胞膜往往溃散而细胞死亡。 |
| 10. | Laboratory techniques now exist that make it possible to fuse the membrances of two different kinds of cells .
目前实验技术有可能融合两种不同的细胞膜。 |
