What structures emit in the core? What are the core functions of the kernel?

The nucleus is limited by the nuclear membrane separating its contents (karyoplasm) from the cytoplasm. The shell consists of two membranes separated by a gap. Both of them are penetrated by numerous pores, due to which the exchange of substances between the nucleus and the cytoplasm is possible. Most eukaryotes contain 1 to 7 nucleoli in the cell nucleus. They are associated with the processes of synthesis of RNA and tRNA.
The main components of the nucleus are chromosomes formed from a DNA molecule and various proteins. Under a light microscope, they are clearly distinguishable only during cell division (mitosis, meiosis). In a non-dividing cell, the chromosomes look like long thin filaments distributed throughout the entire nucleus. The functions of the cell nucleus are as follows: regulation of cell metabolism, division and death; preservation of hereditary information; chromatin spiralization; chromatin despiralization; DNA replication synthesis of messenger RNA; initiation of protein synthesis; interaction with cellular structures through receptors.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
