|---|---|---|---|---|---|
| Autosome | Any chromosome that is not a sex chromosome
🗑
|
||||
| Centromere | The region of the chromosome that holds the two sister chromatids together during mitosis
🗑
|
||||
| Chromatid | One of the two strands of a chromosome that become visible during meiosis or mitosis
🗑
|
||||
| Diploid | A cell that contains two haploid sets of chromosomes
🗑
|
||||
| Haploid | Describes a cell, nucleus, or organism that has only one set of unpaired chromosomes
🗑
|
||||
| Homologous Chromosome | Chromosomes that have the same sequence of genes, that have the same structure, and that pair during meiosis
🗑
|
||||
| Anaphase | A phase of mitosis and meiosis in which the chromosomes separate
🗑
|
||||
| Binary Fission | A form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size
🗑
|
||||
| Cell Cycle | A repeating set of events in the life of a cell
🗑
|
||||
| Cell Plate | The precursor of a new plant cell wall that forms during cell division and divides a cell into two
🗑
|
||||
| Histone | A type of protein molecule found in the chromosomes of eukaryotic cells but not prokaryotic cells
🗑
|
||||
| Centrosome | Contains centrioles and move toward opposite poles of the cell during prophase
🗑
|
||||
| Cytokinesis | The division of the cytoplasma of a cell
🗑
|
||||
| G1 Phase | The first stage of interphase, where offspring cells grow to mature size
🗑
|
||||
| G2 Phase | A time during which the cell prepares for cell division
🗑
|
||||
| Interphase | A period between two mitotic or meiotic divisions during which the cell grows, copies its DNA, and synthesizes proteins
🗑
|
||||
| Meiosis | A process in cell division during which the number of chromosomes decreases to half the original number by two divisions of the nucleus, which results in the production of sex cells
🗑
|
||||
| Mitosis | In eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes
🗑
|
||||
| Prophase | The first stage of mitosis and meiosis in cell division
🗑
|
||||
| S Phase | The second phase in Interphase where DNA is copied (synthesized)
🗑
|
||||
| Telophase | The final stage of mitosis or meiosis, during which a nuclear membrane forms around each set of new chromosomes
🗑
|
||||
| Crossing Over | The exchange of genetic material between homologous chromosomes during meiosis
🗑
|
||||
| Gamete | A haploid reproductive cell that unites with another haploid reproductive cell to form a zygote
🗑
|
||||
| Asexual Reproduction | Reproduction that doesn't involve the union of gametes and in which a single parent produces offspring that are genetically identical to the parent
🗑
|
||||
| Oogenesis | The production, growth, and maturation of an egg or ovum
🗑
|
||||
| Spermatogenesis | The process by which male gametes form
🗑
|
||||
| Metaphase | One of the stages of mitosis and meiosis, during which all of the chromosomes move to the cell's equator
🗑

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.
