(biochemistry) a long linear polymer of nucleotides found in the nucleus but mainly in the cytoplasm of a cell where it is associated with microsomes
Small vesicles in the cytoplasm of liver cells where oxidative metabolism of alcohol takes place.
deoxyribonucleic acid, the material that contains the information that determines inherited characteristics
two strands of nucleotides wound about each other; structure of DNA. looks like a twisted ladder.
the readily stainable substance of a cell nucleus consisting of DNA and RNA and various proteins
Material present in the cytoplasm of all eukaryotic cells, important during cell division; the microtubule-organizing center.
a specialized condensed region of each chromosome that appears during mitosis where the chromatids are held together to form an X shape
the period of the cell cycle during which the nucleus is not undergoing division, typically occurring between mitotic or meiotic divisions
the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes
The stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle
the stage of meiosis or mitosis when chromosomes move toward opposite ends of the nuclear spindle
the final stage of mitosis or meiosis, during which a nuclear membrane forms around each set of new chromosomes
reproduction that does not involve the union of gametes and in which a single parent produces offspring that are genetically identical to the parent
A double membrane across the midline of a dividing plant cell, between which the new cell wall forms during cytokinesis.
