|---|---|---|---|---|---|
| where dose mitosis take place | in human body (somatic) cells
🗑
|
||||
| mitosis | chromosomes multiply and divide when the cell reproduces producing daughter cells that are identical to parent cell
🗑
|
||||
| chromatin | uncoiled strands of DNA
🗑
|
||||
| chromosomes | coiled chromatin; contains genes
🗑
|
||||
| homologous pairs | chromosome pairs that are structurally similar and contain information for some genes; (can different expression of information on those genes)
🗑
|
||||
| mitosis occurs in human body (somatic) cells | these are every cell but the egg or sperm
🗑
|
||||
| How many cells dose somatic (body) cells have | 46 cells
🗑
|
||||
| how many homologous chromosome pairs are there | 23 pairs
🗑
|
||||
| diploid cells | contain all homologous pairs of chromosomes
🗑
|
||||
| Interphase | chromosomes (in form of chromatin) and organelles replicate
🗑
|
||||
| Mitosis | chromosomes divide
🗑
|
||||
| Prophase | chromatin coils into chromosomes (hint: each chromosomes now is made up of 2 chromatids joined by a centromere)
🗑
|
||||
| prophase | nuclear membrane disappears
🗑
|
||||
| Metaphase | chromosomes move to the center of the cell (the equator)
🗑
|
||||
| Anaphase | chromosomes divide and chromatids separate (pulled apart)
🗑
|
||||
| anaphase | chromatides are pulled to opposite sides pulled by spindle fibers
🗑
|
||||
| telophase | centroles and spindle fibers disappear
🗑
|
||||
| telophase | chromaatids unwind back into chromatin
🗑
|
||||
| telophase | neclear membrane reforms
🗑
|
||||
| cytokinesis | cytoplasm starts to divide into new cells and parent cells divide
🗑
|
||||
| cytokinesis | there are now 2 daughter cells that have DNA identical to the parent cell
🗑

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.
