|---|---|---|---|---|---|
| Mitosis | -----Process by which the hereditary material in the parent CELL replicates and divides into two (2) IDENTICAL daughter nuclei (cells).
🗑
|
||||
| Diploid (number) | the total number of chromosomes in normal body cells; two matching homologs of each kind
🗑
|
||||
| Chromosome(s) | a threadlike body in the cell nucleus that carries the genes in a linear order
🗑
|
||||
| Interphase | Interphase ‘RESTING PHASE’ which occurs between mitotic cycles. The cell grows and replicates here.
🗑
|
||||
| Crossing over | the interchange of sections between pairing homologous chromosomes during the prophase of meiosis
🗑
|
||||
| Anaphase | chromosomes move to OPPOSITE poles
🗑
|
||||
| Haploid/Monoploid | hapliod (of a cell or nucleus) having a single set of unpaired chromosomes. monoploid having the basic or haploid number of chromosomes.
🗑
|
||||
| Daughter nuclei | daughter nuclei The nuclei that result from the division of a single nucleus.
🗑
|
||||
| Tetrad | A four-part structure that forms during the prophase of meiosis and consists of two homologous chromosomes, each composed of two sister chromatids.
🗑
|
||||
| Gametogenesis | Gametogenesis( production of the games)
🗑
|
||||
| Meiosis | (genetics) cell division that produces reproductive cells in sexually reproducing organisms
🗑
|
||||
| Metaphase | the second stage of mitosis
🗑
|
||||
| Cytokinesis | ----The cell membrane pinches in and the CYTOPLASM divides into two (2).
🗑
|
||||
| Disjunction | disjunction happens when homologous chromosomes move apart toward the opposite poles of the cell in anaphase I.
🗑
|
||||
| Variation | Variation happen during Crossing over in prophase I
🗑
|
||||
| Replication | The process when the DNA makes a copy of itself before cell division
🗑
|
||||
| Synapsis | the side by side pairing of homologous maternal and paternal chromosomes at the start of meiosis
🗑
|
||||
| Prophase | Prophase first phase, double chromosomes are VISIBLE
🗑
|
||||
| Centrioles | one of two tiny structures located in the cytoplasm of animal cells near the nuclear envelope
🗑

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.
