Budowa jądra komórkowego i jego funkcja

Episode Topics: 🟡 Structure of the Cell Nucleus (Nuclear Envelope, Chromatin, Nucleolus) 🟡 Functions of the Cell Nucleus --- The nucleus is usually found singly in a cell. Its location is central or peripheral. The organelle is roughly spherical, with a diameter ranging from a few to several dozen micrometers. The structure of the cell nucleus is as follows: the nuclear envelope, which protects the interior of the nucleus, i.e., the nucleoplasm. Within the nucleoplasm, also known as karyolymph, are the chromatin and nucleoli. Remember that the structure of the cell nucleus is described differently in different books. The division I present in the video is a sort of average I drew from various books. The structure of the cell nucleus is presented in detail in the video :) When describing the cell nucleus, functions are another important point. They are as follows: The nucleus stores most of the cell's genetic information. Over 90%. The remainder is stored in mitochondria and plastids. The cell nucleus's role is to participate in the transmission of genetic information, which regulates cell metabolism, growth, and function. First, to the daughter cell, and second, into RNA and later protein. Chromosome subunits are also formed in the nucleus, which are later transferred to the cytoplasm. --- Books I used: 🟩 http://bitly.ws/zJfk - Basics of Human Biology 🟩 http://bitly.ws/zJfp - Botany Part 1 🟩 http://bitly.ws/zJfg - Structural Basics of Cell Biology Chapters 0:05 Episode Topic 0:11 Introduction 0:43 Structure of the Cell Nucleus 1:14 Nuclear Envelope (Structure) 2:49 Chromatin (Euchromatin, Heterochromatin) 4:09 Nucleolus 4:34 Functions of the Cell Nucleus 5:17 Summary
