| What is mitosis? | The division of the nucleus in 4 phases
🗑
|

| What happens in the metaphase? | Chromosomes line up across the center of the cell and each chromosome is connected to a spindle fiber
🗑
|
||||
| What happens in the anaphase? | Sister chromatids separate into individual chromosomes and are pulled apart
🗑
|
||||
| What happens in the telophase? | Chromosomes gather at opposite ends of the cell and 2 new nuclear membranes form around them
🗑
|

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.
