Cell nucleus-structure and function

HELLO FRIENDS i am Mohammed Sameer in this video we are going to learn a important topic about cell nucleus its structure and function facts about nuclues The Nucleus varies in size from species to species of cells and bacteria and also can appear differently depending on the kinds of cells they are present in. The nucleus is on such vital importance to the cell because it contains the DNA that the cell needs to synthesize proteins and regulate mostly every other aspect of its function. During cell reproduction, the nucleus breaks apart and the genetic material it contains is replicated to form exact copies that are transferred to the daughter cell. It also contains the Nucleolus, an organelle responsible for the production ribosomes for the cell. It is protected by the nuclear membrane, which regulates what can enter and exit the nucleus. It lets some small water-soluble molecules pass directly through the membrane itself while keeping larger molecules such as the DNA contained in the nucleus inside. However, when nucleic acids need to enter or exit the nucleus, they can pass through one of the nuclear pores, which are openings in the membrane that allow substances to pass into or out of the nucleus. The nucleus is also known as the "brain of the cell" due to its use in controlling the cell's actions by the DNA it holds. the fundamental unit of life class 9 the fundamental unit of life class 9 notes the fundamental unit of life class 9 questions and answers the fundamental unit of life notes fundamental unit of life class 9 important questions the fundamental unit of life class 9 worksheet with answers fundamental unit of life class 9 notes pdf fundamental unit of life class 9 important questions pdf the fundamental unit of life class 9 pdf class 9 fundamental unit of life chapter 5 the fundamental unit of life the fundamental unit of life class 9 notes pdf class 9 fundamental unit of life notes biology class 9 fundamental unit of life cell class 9 extra questions and answers the fundamental unit of life class 9 answers notes of fundamental unit of life class 9 science the fundamental unit of life notes of fundamental unit of life class 9 class 9 the fundamental unit of life notes notes of the fundamental unit of life the fundamental unit of life in hindi the fundamental unit of life class 9 test the fundamental unit of life solution fundamental unit of life class 9 solutions the fundamental unit of life class 9 extra questions notes on fundamental unit of life the fundamental unit of life class 9 worksheet notes of the fundamental unit of life class 9 the fundamental unit of life class 9th fundamental unit of life class 9th the fundamental unit of life cell class 9 the fundamental unit of life extra questions the fundamental unit of life class 9 mcq questions cell the fundamental unit of life class 9 notes cell fundamental unit of life class 9 notes fundamental unit of life class 9 test class 9 science fundamental unit of life notes important questions of fundamental unit of life notes on fundamental unit of life class 9 notes of chapter the fundamental unit of life cell the fundamental unit of life class 9 class 9 science chapter 5 the fundamental unit of life fundamental unit of life class 9 objective questions fundamental unit of life extra questions fundamental unit of life class 9 extra questions the fundamental unit of life notes class 9 cell the basic unit of life class 9 extra questions of cell class 9 the fundamental unit of life class 9 notes in hindi chapter 5 fundamental unit of life assignment on fundamental unit of life for class 9 the fundamental unit of life cell class 9 notes fundamental unit of life in hindi the fundamental unit of life important questions questions on cell class 9 notes on the fundamental unit of life class 9 notes for fundamental unit of life notes of chapter fundamental unit of life class 9 science chapter the fundamental unit of life the fundamental unit of life class 9 in hindi chapter the fundamental unit of life cbse class 9 science biology notes fundamental unit of life class 9 biology fundamental unit of life class 9 biology chapter fundamental unit of life notes fundamental unit of life mcq fundamental unit of life notes class 9 class 9 biology the fundamental unit of life video the fundamental unit of life class 9 important questions extra questions for class 9 science fundamental unit of life questions on fundamental unit of life for class 9 class 9 biology the fundamental unit of life notes fundamental unit of life class 9 questions class 9 fundamental unit of life extra questions the fundamental unit of life mcq class 9 science chapter fundamental unit of life class 9 fundamental unit of life questions extra questions of fundamental unit of life
