The process of nuclear division that requires the cell to replicate its DNA.
What is mitosis?
100
When cells in a tissue undergo transformation and divide uncontrollably, this can lead to the development of _____________.
What is Cancer?
100
Two nuclear divisions, but only one DNA replication that occurs only in germ cells and gives rise to 4 haploid cells.
What is meiosis?
100
Production of progeny that is GENETICALLY IDENTICAL to the parents.
What is asexual reproduction?
200
Interphase (G1, S-Phase, G2), M-Phase and Cytokinesis
What is the Cell Cycle?
200
Prophase, metaphase, anaphase and telophase
What are stages of mitosis
200
Two characteristics of cancerous cells
What are uncontrollable cell division/ metastasis?
200
Process that occurs ONLY during meiosis and contributes to genetic diversity.
What is crossing over?
200
The offspring product of asexual reproduction are consider to be these.
What are clones?
300
After cell division some cells no longer to divide and arrests in this stage the cell cycle.
What is G1 (or G0)?
300
Prokariotic cells reproduce by this mechanism
What is binary fission?
300
Mass of cells that could be malignant or benign.
What is a tumor?
300
Germ cells undergo meiosis and form these specialized cells.
What are gametes?
300
A map of the chromosomes of an organism, where structure, number and banding patterns of the chromosomes could be studied.
What is karyotype?
400
Stage of the cell cycle in which DNA replication occurs
What is S-phase (interphase)?
400
These are the types of microtubules that comprise the mitotic spindle
What are kinetochore and polar microtubules?
400
Genes that encode proteins that normally turn off cell division but are inactivated by mutations in cancer are ___________________________. Genes that normally encode proteins that stimulate cell division but are hyperactivated in cancer are ________________.
What is tummor suppresor genes / oncogenes?
400
Stage of meiosis where crossing over occurs and the physical structures that form during this process.
What are prophase and chiasmata?
400
Haplontic, Diplontic and Alternation of Generations.
What are sexual life cycles?
500
Proteins-DNA complex present in DNA coiling or condensation.
What is nucleosome?
500
the Cdk-Cyclin complex can regulate the cell cycle in specific checkpoints by __________________ of _______________
What are phosphorylation / Retinoblastoma (Rb)?
500
These cancer treatments act in different ways. The first inhibits the formation of the mitotic spindle, the second prevents DNA synthesis and the third blocks a growth factor receptor.
What are taxol, 5-FU and herceptin?
500
During mitosis, 2 cells identical (diploid) to the parental cell are produced. Meiosis produces __________ cells that are ____________.
What are 4 cells and haploid?
500
Genetic diversity, random selection of half of the chromosome set and no two individuals are identical.
