|---|---|---|---|---|---|
| mitosis | cell divide of body cells
🗑
|
||||
| cytokinesis | Cytokinesis is the process during cell division in which the cytoplasm of a single eukaryotic cell is divided to form two daughter cells.
🗑
|
||||
| replication | the process of producing two identical replicas from one original DNA molecule.
🗑
|
||||
| cell cycle | The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells
🗑
|
||||
| chromosomes | a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
🗑
|
||||
| chromatid | each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA.
🗑
|
||||
| centromere | the point on a chromosome by which it is attached to a spindle fiber during cell division.
🗑
|
||||
| chromatin | the material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed. It consists of protein, RNA, and DNA
🗑
|
||||
| diploid | containing two complete sets of chromosomes, one from each parent.
🗑
|
||||
| interphase | the resting phase between successive mitotic divisions of a cell, or between the first and second divisions of meiosis.
🗑
|
||||
| crossing over | the exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring.
🗑
|
||||
| tetrad | A tetrad is the foursome during meiosis made by two homologous chromosomes that have each already replicated into a pair of sister chromatids
🗑
|
||||
| synapsis | s the pairing of two homologous chromosomes that occurs during meiosis
🗑
|
||||
| polar bodies | A polar body is a small haploid cell that is formed concomitantly as an egg cell during oogenesis, but which generally does not have the ability to be fertilized
🗑
|
||||
| gametogenesis | the process in which cells undergo meiosis to form gametes.
🗑
|
||||
| gonad | The gonads are the reproductive organs for both males and females
🗑
|
||||
| gamete | a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.
🗑
|
||||
| ovum/ova | is the name for the haploid female reproductive cell, or gamete.
🗑
|
||||
| sperm | Sperm is the male reproductive cell
🗑
|
||||
| hapliod | having a single set of unpaired chromosomes
🗑

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.
