explain the structure of nucleus
Structure: it contains 1 nuclear envelope ( gateway to the nucleus) 2 Chromosomes ( genetic containers) 3 nucleolus ( preassembly point for ribosomes)
Function:it directs the chemical reactions in cells by transcribing genetic information from DNA into RNA. nucleus also stores genetic information & transfers it during cell division from one cell to the next.it Controlss cell's genetic program & metabolic activities.
The nucleus is surrounded by a structure called the nuclear envelope. This membrane separates the contents of the nucleus from the cytoplasm. The cell's chromosomes are also housed within the nucleus. Chromosomes contain DNA which provides the genetic information necessary for the production of other cell components and for the reproduction of life.
