Centromere

... centromere is a region of a eukaryotic chromosome where the kinetochore is assembled. Thus, it is the site where spindle fibers of the mitotic spindle attach to the chromosome during mitosis . It is also the site of the primary constriction visible in microscopy images of chromosomes. ...

Chromatid

... of mitosis or meiosis . Each chromosome consists of two exactly identical (" sister ") chromatids. After they have been pulled apart by the mitotic spindle , chromatids are called "chromosomes". Sister chromatids are joined at a point called the centromere . In non-gametic, non-dividing human ...

Cytoskeleton

... with dyneins and kinesins they transport organelles like mitochondria or vesicles .) the axoneme of cilia and flagella the mitotic spindle synthesis of the cell wall in plants. The prokaryotic cytoskeleton The cytoskeleton was previously considered to be a feature only ...

Meiosis

... earlier, meiotic nuclear division consists of two stages, called meiosis I and meiosis II . It starts with a cell in the same state as does a mitotic division. However, the alignment of chromosomes for prophase is different. Homologous chromosomes join into tetrads (so called because each tetrad ...

Microbiology

... 12 to 24 hours for Mycobacterium tuberculosis ) Cells can easily survive in isolation from other cells Unicellular eukaryotes reproduce by mitotic division and prokaryotes by binary fission . This allows for the propagation of genetically identical ( clonal ) populations. They may be ...

Mitotic spindle

... The mitotic spindle is a structure of the eukaryotic cytoskeleton involved in mitosis and meiosis . It consists of a bundle of microtubules joined at ...

Prophase

... - which replicate independently of mitosis - begin recruiting microtubules (which may be thought of as cellular ropes or poles) and forming a mitotic spindle between them. By increasing the length of the spindle (growing the microtubules), the centrioles push apart to opposite ends of the cell ...

Tubulin

... to be evolutionarily related to tubulin. Delta and epsilon tubulin have been found to localize at centrioles and may play a role in forming the mitotic spindle during mitosis. Pharmacology Tubulins are targets for anticancer drugs like taxol . The anti- gout agent colchicine binds to ...

Zygote

... a sperm cell from a male and an ovum from a female —merge into a single diploid cell called the zygote . Animal zygotes undergo mitotic cell divisions to become an embryo . Other organisms may undergo meiotic cell division at this time (for more information refer to biological ...
