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.
27 de mai. 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.

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.
- Not quite, translation is part of protein synthesis
- 1. Messenger RNA (mRNA) carries the genetic information copied from DNA in the form of a series of three-base code “words,” each of which specifies...
- Yes, but there are some differences to keep in mind. Cytosol has enzymes, fatty acids, sugars, and amino acids, all dissolved within it. It is the...
- The deoxyribose (DNA) and ribose (RNA) are the 2 different sugar components to the structure :)
- We do have 46 chromosomes, 22 pairs of homologous chromosomes + sex chromosomes. Many cells are in G0 stage, so mitosis doesn't happen (somatic cel...
- The picture you are referring to is an image of a section of the endoplasmic reticulum known as the "Rough ER". The ribosomes there create proteins...
- The ribosomes are reversibly attached to the outer surface of the membrane rather than being inserted into the membrane. The proteins produced by E...
- rRNA forms rybosomes, which are organieles that put mRNA and tRNAs close enough so peptide can be made (it's just a factory). And yes, there are ma...
- An enzyme is a type of protein, there are also other types of proteins that aren't enzymes.
The nucleoplasm is the semi-solid fluid inside the nucleus, where we find the chromatin and the nucleolus. You may remember that in prokaryotes, DNA is organized into a single circular chromosome. In eukaryotes, chromosomes are linear structures.
Google Sala de Aula. Estrutura e função do núcleo e ribossomos da célula. Como eles trabalham juntos na produção de proteínas. Introdução. Suponha que você tenha uma informação muito valiosa. Vamos imaginar que essa informação seja um projeto de engenharia.
19 de set. de 2023 · Since the structure of the nucleus is an important milestone for understanding citology and histology, this article will discuss the structure and function of the cell nucleus in an easy to read mode.
