Essential vocabulary for the IBO DP Biology course
Terms in this set (22)
a type of asexual reproduction common among prokaryotes where one cell divides giving rise to two cells, each having the potential to grow to the size of the original cell.
general term for more than 100 diseases that are characterized by uncontrolled, abnormal growth of cells.
a membrane that forms midway between dividing plant cells during cytokinesis and later becomes the cell wall.
a self-replicating cylindrical organelle that is involved in the process of nuclear division.
the region joining the two sister chromatids where it becomes attached to the spindle fibres.
linear strand of DNA bonded to proteins in the nucleus of eukaryotic cells that carries the genetic information.
a family of closely related proteins that regulate the cell cycle in eukaryotic cells.
the division of the cytoplasm and the plasma membrane, following the division of the nucleus, resulting in two cells in mitosis.
the figure formed by the chromosomes in the centre of the spindle during mitosis.
stage in mitosis in which chromosomes become arranged at the equatorial plate.
characteristic of malignant tumours of transferring the disease from one organ to another not directly connected with it.
hollow protein tubes seen during the mitosis of animal cells.
the process where a single cell divides into two identical cells, each containing the same number of chromosomes and genetic content as that of the original cell.
the ratio between the number of cells in mitosis to the total number of cells.
chemical agents that increase the rate of genetic mutation.
a gene that causes normal cells to change into cancerous tumour cells.
first stage of mitosis during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears.
two identical strands of DNA joined by a common centromere.
network of filaments that collectively form a mitotic spindle in mitosis. They are involved in moving the chromosomes during nuclear division.
twisting in the opposite direction to the turns of the double helix during the first stage of mitosis.
the final stage of mitosis in which the separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around them.
abnormal proliferation of cells, either benign or malignant.
