举一反三
- Proteins are the principal constituents of cells and determine not only cell structure but also cell function.
- The sum of all the proteins functioning in a given cell is the cell's ____________, and proteomics is the systematic characterization of this protein complement under a specific set of conditions.
- cell cycle non - specific agents:
- Which of the following connective tissue components is located inthe ECM but not in the ground substance? A: Hyaluronan B: fibronectin C: Proteoglycans D: Collagen bundles E: GAGs
- 细胞外基质的成分不包括 （ ）。 A: 表皮生长因子（EGF） B: 胶原蛋白（Collagen） C: 纤连蛋白（Fibronectin） D: 层粘连蛋白（Laminin）
