Write a short note on nucleus of a cell |
|
Answer» The main structures making up the nucleus are the nuclear envelope, a double membrane that encloses the ENTIRE organelle and isolates its contents from the CELLULAR cytoplasm, and the nuclear matrix (which includes the nuclear lamina), a network within the nucleus that ADDS mechanical supportThis organelle has two major functions: it stores the cell's hereditary MATERIAL, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, KNOWN as eukaryotes, have a nucleus. |
