WebMay 8, 2024 · The Cell Wall. In Figure 3.1.3. 1 b, the diagram of a plant cell, you see a structure external to the plasma membrane called the cell wall. The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell. Fungal and protist cells also have cell walls. WebOne complete unit of an 80S eukaryotic ribosome contains nearly 88 ribosomal proteins (RPs). These proteins have a high ratio of arginine/lysine and specific extension tails to facilitate protein-RNA and protein-protein interactions, respectively. The RPs are encoded by ribosomal protein genes (RPGs) that are evenly distributed in the genome ...
