In the nucleus, areas of euchromatin and heterochromatin can easily be identified. Virtual Slide. Cell Nucleus - function, structure, and under a microscope The nucleus is a specialized organelle that contains double-layer membranes with pores. The main function of the nucleus is to govern cell activities and to carry genetic information to pass to the next generation. This is why we call the nucleus the brain of the cells. [In this figure] The cell nucleus diagram and its structure. Nuclear Labeling | Thermo Fisher Scientific - US Labeling the nucleus typically relies on some type of dye that binds nucleic acids, and depending on how much distinction you need between DNA and RNA and whether or not the cells you're labeling are live or fixed, your choice of stains will vary.

nucleus structure

Nucleus- Definition, Structure, Parts, Functions, Diagram 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.

4.3 Eukaryotic Cells - Biology 2e | OpenStax Unlike prokaryotic cells, eukaryotic cells have: 1) a membrane-bound nucleus; 2) numerous membrane-bound organelles such as the endoplasmic reticulum, Golgi apparatus, chloroplasts, mitochondria, and others; and 3) several, rod-shaped chromosomes. Because a membrane surrounds eukaryotic cell's nucleus, it has a "true nucleus.".

Electron Microscopic Structure of a Typical Bacterial Cell The characteristic of a bacterial nucleus is the absence of nuclear membrane, nucleolus, chromonemata and nuclear sap. Such a nucleus is termed as nucleoid or genophore. Under electron microscope the nucleoid appears to be fibrillar and composed of a double or single stranded DNA.
