PBSC-BSC-The Cell Cycle Mitosis
Question | Answer |
---|---|
The phase of interphase when the DNA is replicated, is known as _______. | Synthesis - S |
The portion of mitosis wherein the DNA condenses and two poles are established. | Prophase |
The portion of mitosis wherein the chromosomes line up at the spindle equator. | Metaphase |
Cells which are exact genetic copies of the parent cell. | Clones |
The portion of mitosis that includes: chromosomes re-condensing, a new nuclear envelope forms for each cell; cytokinesis occurs here also. | Telophase |
The nuclear division mechanism which results in clones for growth and development. | mitosis |
The nuclear division mechanism which results in hapoid (1/2 the chromosome number) cells for reproduction | meiosis |
The "arms and legs" of the chromosome (X shaped) | Chromatids |
Cells which undergo division to become sex cells. | germ cells |
All cells in an organism which are not germ cells. | Somatic Cells |
The total number of chromosome pairs in a diploid human cell. | 23 |
The region of the duplicated chromosome where the sister chromatids are joined. | Centromere |
What percentage of the cell's life cycle is spent in Interphase? | 90% |
The division of the cytoplasm which occurs during telophase is called _______. | Cytokinesis |
DNA which is complexed with proteins. | Chromosomes |
Chromosome pairs which are the same type (shape, number, same genes). | Homologous |
The term for cells having two chromosomes of each type. | Diploid |
The total number of chromosomes in a diploid human cell. | 46 |
The division of the cytoplasm in animal cells (during telophase). | Cleavage Furrow |
The G1 phase of interphase stands for _______. | Growth or GAP |
The portion of mitosis wherein the sister chromatids are separated and each is pulled toward an opposite pole. | Anaphase |
The division of the cytoplasm in plant cells (during telophase). | Cell Plate |
The term for cells having half the normal number of chromosomes. | Haploid |
Cell division that results in identical daughter cells for growth and repair is _______ while cell division that results in gametes is _______. | Mitosis; meiosis |
Cell division in prokaryotes is known as ______ _______. | Binary fission |
Checkpoints to determine that it is safe to continue mitosis occur in _____, _____, and _____. | G1, G2, M |
If a cell doesn't receive a go ahead at the checkpoint, it enters this phase: | Go |

Tumors whose cells remain together in one place are _______ tumors. | Benign |
Tumors whose cells break off and can form new tumors at distant sites are _______ tumors. | Malignant |
The term for when malignant tumors spread to other parts of the tissue or body is: | Metastatic |
Normal healthy cells stop growing when they become crowded; this is known as: | Density dependent inhibition |
Cancer cells that have lost the ability to stop dividing when not attached to a substrate have lost their: | Anchorage dependence |
