31 de oct. de 2023 · Learn about the nucleus, the command center of a eukaryotic cell that contains the cell's hereditary information and controls its growth and reproduction. Explore the structure and functions of the nuclear membrane, nucleoplasm, nucleolus, chromosomes, and chromatin.
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, a network within the nucleus that adds mechanical support.
6 de nov. de 2019 · Learn about the nucleus, the command center of a eukaryotic cell that contains genetic material and regulates cell growth and reproduction. Find out how the nucleus is bounded by a membrane, contains chromatin and nucleolus, and synthesizes proteins and ribosomes.
Aquí veremos con más detalle la estructura del núcleo y los ribosomas. ¿Todas las células tienen solo un núcleo? El núcleo (en plural núcleos) alberga el material genético de la célula, el ADN, y es también el lugar donde se producen los ribosomas, las máquinas celulares que sintetizan proteínas.
4 de feb. de 2021 · Nucleus is a membrane-bound organelle that houses DNA, the genetic material of a eukaryotic cell whereas nucleolus is a sub-organelle found within the nucleus containing RNA and is responsible for ribosome synthesis.
Learn about the nucleus, the control center of the cell, and its components, such as the nucleolus, the nuclear envelope, and the nucleoplasm. Watch a video and read the transcript to understand how the nucleus regulates gene expression and protein synthesis.
