---|---|---|---|---|---|
Chromosome | in a eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA
🗑
|
||||
Histones | a type of protein molecule found in the chromosomes of eukaryotic cells but not prokaryotic cells
🗑
|
||||
Chromatid | one of the two strands of a chromosome that become visible during meiosis or mitosis
🗑
|
||||
Centromere | the region of the chromosome that holds the two sister chromatids together during mitosis
🗑
|
||||
Chromatin | the material that makes up both mitotic and interphase chromosomes; a complex or proteins and DNA strands that are loosely coiled such that translation and transcription can occur
🗑
|
||||
Sex Chromosome | one of the pair of chromosomes that determine the sex of an individual
🗑
|
||||
Autosome | any chromosome that is not a sex chromosome
🗑
|
||||
Homologous Chromosome | chromosomes that have the same sequence of genes, that have the same structure, and that pair during meiosis
🗑
|
||||
Karyotype | a micrograph of the array of chromosomes visible in a cell during metaphase; a graphical display that shows an individuals chromosomes arranged in homologous pairs and in order of diminishing size
🗑
|
||||
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
🗑
|
||||
Binary Fission | a form of asexual reproduction in single-celled organisms by which one cell divides into two cells of the same size
🗑
|
||||
Mitosis | in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes
🗑
|
||||
Asexual Reproduction | reproduction that does not involve the union of gametes and in which a single parent produces offspring that are genetically identical to the parent
🗑
|
||||
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
🗑
|
||||
Gamete | a haploid reproductive cell that unites with another haploid reproductive to form a zygote
🗑
|
||||
Interphase | a period between two mitotic or meiotic divisions during which the cell grows, copies its DNA, and synthesizes proteins
🗑
|
||||
Cytokinesis | the division of the cytoplasma of a cell; cytokinesis follows the division of the cell's nucleus by mitosis or meiosis
🗑
|
||||
Prophase | the first stage of mitosis and meiosis in cell division; characterized by the condensation of the chromosomes and the dissolution of the nuclear envelope
🗑
|
||||
Spindle Fiber | one of the microtubules that extend across a dividing eukaryotic cell; assists in the movement of chromosomes
🗑
|
||||
Meta Phase | one of the stages of mitosis and meiosis, during which all of the chromosomes move to the cell's equator
🗑
|
||||
Anaphase | a phase of mitosis and meiosis in which the chromosomes separate
🗑
|
||||
Telophase | the final stage of mitosis or meiosis, during which a nuclear membrane forms around each set of new chromosmes
🗑
|
||||
Cell Plate | the precursor of a new plant cell wall that forms during cell division and divides a cell into two
🗑
|
||||
🗑

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.
