The cell nucleus (from Latin nucleus or nuculeus 'kernel, seed'; pl.: nuclei) is a membrane-bound organelle found in eukaryotic cells. Eukaryotic cells usually have a single nucleus, but a few cell types, such as mammalian red blood cells, have no nuclei, and a few others including osteoclasts have many.
16 de abr. de 2024 · Nucleus, in biology, a specialized structure occurring in most cells (except bacteria and blue-green algae) and separated from the rest of the cell by a double layer, the nuclear membrane. The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes.

Typically, the nucleus is the most prominent organelle in a cell. The nucleus (plural = nuclei) houses the cell’s DNA in the form of chromatin and directs the synthesis of ribosomes and proteins. Let us look at it in more detail ( Figure 5.8.1 5.8. 1 ).
19 de set. de 2023 · The cell nucleus is the most noticeable organelle within the eukaryotic cell, and perhaps the most important and defining feature of the eukaryotic cells. Most of the genetic material (DNA) is contained in the nucleus, while a small amount of it is found in mitochondria.

O núcleo (plural, núcleos) abriga o material genético da célula, ou DNA, e é também o local de síntese de ribossomos, as máquinas celulares que montam as proteínas. Dentro do núcleo, a cromatina (DNA enrolado em volta de proteínas, descrita mais abaixo) é armazenada em uma substância gelatinosa chamada nucleoplasma.
The nucleus (plural, nuclei) houses the cell’s genetic material, or DNA, and is also the site of synthesis for ribosomes, the cellular machines that assemble proteins. Inside the nucleus, chromatin (DNA wrapped around proteins, described further below) is stored in a gel-like substance called nucleoplasm.
