  2. Nucleoid - Wikipedia

    en.wikipedia.org/wiki/Nucleoid

    The nucleoid reorganizes in stationary phase cells suggesting that the nucleoid structure is highly dynamic, determined by the physiological state of cells. A comparison of high-resolution contact maps of the nucleoid revealed that the long-range contacts in the Ter macrodomain increased in the stationary phase, compared to the growth phase. [126]

  3. Cell nucleus - Wikipedia

    en.wikipedia.org/wiki/Cell_nucleus

    Diagram of the nucleus showing the ribosome-studded outer nuclear membrane, nuclear pores, DNA (complexed as chromatin), and the nucleolus. The nucleus contains nearly all of the cell's DNA, surrounded by a network of fibrous intermediate filaments called the nuclear matrix, and is enveloped in a double membrane called the nuclear envelope.

  4. Chromosome - Wikipedia

    Instead, their DNA is organized into a structure called the nucleoid. [27] [28] The nucleoid is a distinct structure and occupies a defined region of the bacterial cell. This structure is, however, dynamic and is maintained and remodeled by the actions of a range of histone-like proteins, which associate with the bacterial chromosome. [29]

  5. Cell (biology) - Wikipedia

    en.wikipedia.org/wiki/Cell_(biology)

    Structure of a typical animal cell Structure of a typical plant cell. Plants, animals, fungi, slime moulds, protozoa, and algae are all eukaryotic. These cells are about fifteen times wider than a typical prokaryote and can be as much as a thousand times greater in volume.

  6. DNA - Wikipedia

    en.wikipedia.org/wiki/DNA

    Cell division is essential for an organism to grow, but, when a cell divides, it must replicate the DNA in its genome so that the two daughter cells have the same genetic information as their parent. The double-stranded structure of DNA provides a simple mechanism for DNA replication .

  7. Chromatin - Wikipedia

    en.wikipedia.org/wiki/Chromatin

    Prokaryotic cells have entirely different structures for organizing their DNA (the prokaryotic chromosome equivalent is called a genophore and is localized within the nucleoid region). The overall structure of the chromatin network further depends on the stage of the cell cycle.

    en.wikipedia.org/wiki/Nucleolus

    The nucleolus (/ nj uː ˈ k l iː ə l ə s, ˌ nj uː k l i ˈ oʊ l ə s /; pl.: nucleoli /-l aɪ /) is the largest structure in the nucleus of eukaryotic cells. [1] It is best known as the site of ribosome biogenesis. The nucleolus also participates in the formation of signal recognition particles and plays a role in the cell's response to ...
