MITOSIS VOCABULARY
Question | Answer |
---|---|
Mitosis | Process by which the hereditary material in the parent CELL replicates and divides into two (2) IDENTICAL daughter nuclei (cells) |
Cell cycle- | continuous growth and division of the cells |
Cell division | is a complex series of changes in the NUCLEUS of the cell, resulting into new cells. |
Replication | the genetic material in the nucleus of the parent cell doubles |
Chromatin | uncoiled dna and RNA( proteins), are thin twisted thread |
Chromatid | Half of a duplicated chromosome |
Chromosome | Cell structures that are SHORTENED, THICK rod- shaped chromatids and made of DNA and proteins, and contains hereditary information |
Centromere | a specialized structure on the chromosome, which holds sister chromatids together |
Cytokinesis | The cell membrane pinches in and the CYTOPLASM divides into two This can occur in late anaphase or after Telophase |
Centrioles | Organelle that helps with cell division in animal cells. The centrioles help in the formation of the spindle fibers that separate the chromosomes during cell division (mitosis). |
Daughter nuclei | The two nuclei that result from the division of a single nucleus, |
Clone | a group of identical cells that derive from the same cell (identical copy) |
Diploid (number) | 2n/ 46 chromosomes in every somatic cell |
Asexual reproduction | a type of reproduction by which offspring arise from ONLY A single organism, and inherit the genes of that parent only(identical) |
Interphase | Is the ‘RESTING PHASE’ which occurs between mitotic cycles. The cell grows and replicates here. |
Cell plate | a plate that develops at the midpoint between the two groups of chromosomes in a dividing cell and that is involved in forming the wall between the two new daughter cells. |
Binary fission | EQUAL division of the cytoplasm |
Grafting | cutting & splicing two different plants |
Cancer | Gene mutations in a cell can result in uncontrolled cell division |
Prophase | first phase, double chromosomes are VISIBLE nuclear membrane disappears aster and spindle fibers appear |
