🗑
|

| exit from cell cycle-nondividing cell | G0
🗑
|

| g2 phase | cell growth continues, enzymes & other proteins synthesized, replication of centrosome completed.
🗑
|
||||
| Mitotic(M) Phase cycle | Prophase, Metaphase, Anaphase, Telophase
🗑
|

| cellular division produces | 2 identical daughter cells during Mitosis
🗑
|

| astral ray of spindle fibers | microtubules extend between pairs of centrioles
🗑
|
||||
| metaphase | equator, chromosomes line up *countable
🗑
|
||||
| anaphase | centromere divides & chromatids seperate moving towards centrioles at opposite poles- pulled apart by spindle fibers

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.
