|---|---|---|---|---|---|
| Cell cycle | process of cellular reproduction, occurring in three main stages
🗑
|
||||
| Chromatin | relaxed form of dna in the nucleus of a cell
🗑
|
||||
| Chromosome | dna-containing structure that carries genetic material from one generation to another
🗑
|
||||
| Cytokinesis | third main stage of the cell division by stimulating production of proteins required for mitosis
🗑
|
||||
| Interphase | first stage of the cell cycle, during which a cell grows, matures and replicates its dna
🗑
|
||||
| Mitosis | second main stage of the cell cycle during which the cell's replicate dna divides and two genetically identical diploid daughter cells are produced
🗑
|
||||
| Anaphase | third stage of mitosis in which sister chromatids are pulled apart and microtublues, along with motor proteins move the chomosomes to opposite poles of the cell
🗑
|
||||
| Centromere | cell structure that joins two sister chromatids
🗑
|
||||
| Metaphase | second stage of mitosis in which motor proteins pull sister chromatids to the cell's equator
🗑
|
||||
| Prophase | first stage of mitosis, during which the cell's chromatin condenses into chromosomes
🗑
|
||||
| Sister chromatid | structure that contains identical dna copies and formed during dna replication
🗑
|
||||
| Spindle apparatus | structure made of spindle fibers, centrioles, and aster fibers that is involved in moving and organizing chromosomes before the cell divides
🗑
|
||||
| Telophase | last stage of mitosis in which nucleoli reappear. Two new nuclear memberanes begin to form, but the cell has not yet completely divided
🗑
|
||||
| Apoptosis | programmed cell death
🗑
|
||||
| Cancer | uncontroled growth and division of cells that can be caused by changes in control of the cell cycle and also may be caused by environmental factors
🗑
|
||||
| Carcinogen | cancer-causing substance
🗑
|
||||
| Cyclin | one of the specific proteins that regulate the cell cycle
🗑
|
||||
| Stem cell | unspecialized cell that can develop into a specialized cell under the right conditions
🗑
|
||||
| dependent kinase | enzyme to which cyclin binds during interphase and mitosis, triggering and controlling activities during the cell cycle
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
