Mitosis/meiosis

Vocabulary

QuestionAnswer
cell cycle process of celluar reproduction, occuring in 3 main stages, interphase, mitosis, and cytokinesis
interphase 1st stage of cell cycle during which the cell grows, matures and replicates DNA
mitosis 2nd main stage of the cell cycle, during which the cell's replicated DNA divides and two genetically identical diploid daugher cells are produced.
cytokinesis 3rd main stage of the cell cycle during which the cell's cytoplasm divides , creating a new cell.
chromosome DNA containing structure that carries genetic material from one generation to another.
chromatin relaxed form of DNA in the nucleus of a cell
prophase where the cell spends most of it's time. the cell's chromatin condenses into chromosomes in the shape of an X
sister chromatid structures that contain identical copies of DNA.
centromere the structure at the centre of the chromosome where two sister chromatids attach.
spindle apparatus includes the fibers, centrioles, and aster fibers. It helps in moving the chromosomes before cell division.
metaphase 2nd stage of mitosis. The sister chromatids are pulled to the center or equater of the cell
anaphse 3rd stage of mitosis. chromatids are pulled away or apart from the equator
telophase the last stage of mitosis. The chromosomes arrive at the poles, the cell begins to relax and decondense.
cytokinesis 3rd main stage of the cell cycle, during which the cell's cytoplasm divides creating a new cell.
cyclin proteins
cancer uncontrolled cell growth and division of cells
carcinogen substances and agents known to cause cancer
apotosis programmed cell death
gene DNA segments
homologous chromosome the chromosomes that make up a pair, one from each parent.
gamete sex cell that has half the number of chromosomes
haploid a cell with n number of chromosomes
fertilization a process by which one haploid gamete combines with another haploid gamete.
diploid a cell that contains 2n number of chromosomes
meiosis where gametes are formed, a type of cell division that reduces the number of chromosomes.
Crossing over a process whereby chromosomal segments are exchanged between a pair of homologous chromosomes
