18 Σεπ 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.

4 Φεβ 2021 · Learn what a nucleus is, how it looks, and what it does in a eukaryotic cell. Find out the parts, functions, and FAQs of the nucleus, the organelle that contains the genetic material DNA.
6 Νοε 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.
The presence of a nucleus is the principal feature that distinguishes eukaryotic from prokaryotic cells. By housing the cell's genome, the nucleus serves both as the repository of genetic information and as the cell's control center.
4 Οκτ 2019 · A cell nucleus is a large organelle in eukaryotic cells that protects and processes most of the DNA. Learn about the structure, function and examples of cell nuclei in plants and animals, and how they differ from prokaryotes and other organelles.
31 Οκτ 2023 · The nucleus is the organelle that houses chromosomes. Chromosomes consist of DNA, which contains heredity information and instructions for cell growth, development, and reproduction. Chromosomes are present in the form of strings of DNA and histones (protein molecules) called chromatin.
29 Οκτ 2023 · The nucleus is a membrane bound organelle that houses the genome and regulates gene expression in eukaryotic cells. It is composed of the nuclear envelope, nuclear lamina, chromatin and nucleolus, and has three main functions: cell compartmentalisation, gene expression and processing of pre-mRNA.
