100
The molecule that is tightly packed together to form chromosomes.
What is DNA?
100
The stage of interphase in which DNA is replicated?
What is S phase?
100
The stage of mitosis in which chromosomes line up in the middle of the cell.
What is Metaphase?
100
An animal with 26 chromosomes in its somatic cells will have this many in its gametes.
What is 13?
100
The phase of the cell cycle that the cell spends most of its time in.
What is Interphase?
200
The region where two sister chromatids are bound together.
What is the centromere?
200
The phase in which the cytoplasm is split between two newly-formed daughter cells.
What is cytokinesis?
200
The stage of mitosis in which the nuclear membrane breaks down and the centrioles and spindle fibers appear.
What is Prophase?
200
A somatic cell with 16 chromosomes going through mitosis will produce 2 daughter cells with this many chromosomes.
What is 16 chromosomes?
200
Process of cell division that produces daughter cells that are IDENTICAL to the parent cell.
What is mitosis?
300
The structure formed when 2 pairs of sister chromotids are grouped together.
What is a tetrad?
300
The cell spends 90% of its time in this phase.
What is interphase?
300
The stage of mitosis in which chromatids are pulled to opposite sides of the cell.
What is Anaphase?
300
The number of chromosomes in the daughter cells after a cell with 38 chromosomes goes through meiosis.
What is 19 chromosomes?
300
The reasons for cells to divide.
What are grow, repair, reproduce/replace?
400
A pair of chromosomes that code for similar traits (one from mother and one from father).
What are homologous chromosomes?
400
The process in which a cell's nucleus divides.
What is mitosis?
400
The stage of mitosis in which spindle fibers attach to chromosomes lined up in the middle of the cell.
What is Metaphase?
400
The number of chromosomes in a somatic cells of an organism that has gametes with 7 chromosomes.
What is 14 chromosomes?
400
The cable-like structures that pull sister chromatids apart during anaphase.
What are spindle fibers?
500
A region of DNA that codes for an individual protein or trait.
What is a gene?
500
The three main phases of the cell cycle.
What are Interphase, Mitosis, and Cytokinesis?
500
The stage of mitosis in which the nuclear membrane starts to reform and a cleavage furrow forms between two daughter cells.
What is Telophase?
500
The number of homologous pairs in an organism with a diploid chromosome number of 30.
What is 15 homologous pairs?
