Eukaryotic chromosome structure refers to the levels of packaging from raw DNA molecules to the chromosomal structures seen during metaphase in mitosis or meiosis.Chromosomes contain long strands of DNA containing genetic information.
The cell is the basic structural and functional unit of all forms of life.Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function.
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells.
The eukaryotes (/ j uː ˈ k ær i oʊ t s,-ə t s / yoo-KARR-ee-ohts, -əts) [3] constitute the domain of Eukaryota or Eukarya, organisms whose cells have a membrane-bound nucleus.All animals, plants, fungi, seaweeds, and many unicellular organisms are eukaryotes.
Eukaryotic Transcription. Eukaryotic transcription is the elaborate process that eukaryotic cells use to copy genetic information stored in DNA into units of transportable complementary RNA replica. [1]
Microtubule and tubulin metrics [1]. Microtubules are polymers of tubulin that form part of the cytoskeleton and provide structure and shape to eukaryotic cells. Microtubules can be as long as 50 micrometres, as wide as 23 to 27 nm [2] and have an inner diameter between 11 and 15 nm. [3]
Eukaryotic [4] Bacterial [4]; Ribosome Sedimentation coefficient 80 S 70 S Molecular mass ~3.2×10 6 Da ~2.0×10 6 Da : Diameter ~250–300 Å ~200 Å Large subunit Sedimentation coefficient
The protoplasmic material of the nucleus including the nucleolus labelled as nucleoplasm.. The nucleoplasm, also known as karyoplasm, [1] is the type of protoplasm that makes up the cell nucleus, the most prominent organelle of the eukaryotic cell.
