Cell Division
Help!

|---|---|---|---|---|---|
| Cytokinesis | Division of Cell into two cells. Happens after Mitosis
🗑
|
||||
| Sister Chromatids | Two identical halves of a chromosome
🗑
|
||||
| Centromere | The center part that binds the two chromatids together
🗑
|
||||
| Human DNA Amount | 46 Chromosomes, 23 Homologous Pairs, 92 Chromatids
🗑
|
||||
| interphase | the time when the cell is not dividing
🗑
|
||||
| nucleolus | this produces the ribosome components and is located inside the nucleus
🗑
|
||||
| Centrosomes | also called microtubule organizing centers (MTOCs) they contain centrioles which create the mitotic spindle
🗑
|
||||
| Prophase I | Nucleoli disappear, Chromatin to Chromosomes, nuclear envelope breaks down, mitotic spindle is created homologous chromosomes pair in tetrads and exchange genes.
🗑
|
||||
| Metaphase I | the mitotic spindle attaches to the chromosomes one from each side per tetrad
🗑
|
||||
| Anaphase I | the tetrads uncouple and the homologous chromosomes are pulled to opposite sides
🗑
|
||||
| Telophase I | a nuclear membrane is created around each pole which creates a haploid nucleus with full chromosomes. Then cytokinesis often occurs.
🗑
|
||||
| Prophase II | the nuclear envelope disappears and spindle fibers develope
🗑
|
||||
| metaphase II | chromosomes align on metaphase plate
🗑
|
||||
| anaphase II | the chromosomes are pulled apart into chromatids and go to the poles
🗑
|
||||
| telophase II | nuclear envelopes reappear at each pole and cytokinesis occurs.
🗑

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.
