PBSC-BSC-The Cell Cycle Mitosis

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
______ occurs when a cell acquires the ability to divide indefinitely. Transformation
A ball of cells that is growing uncontrollably is a _______. Tumor
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
