Reproduction Flashcards
DNA
The genetic material in the cells.
Chromosomes
Chromatin compacted into visible structures.
Cell cycle
The life cycle of a eukaryotic cell.
Interphase
The part of the cell cycle where the cell is not dividing.
Mitosis
Part of the cell cycle where the nucleus divides.
Do prokaryotes undergo or go through the process mitosis.
No, prokaryotic cells do not go through mitosis.
Cytokinesis
The division of the parent cell’s cytoplasm.
In what stage does a cell spend most of it times?
A cell spends most of its time in the interphase stage.
What happens during the prophase stage of mitosis?
The chromatin in the nucleus of a cell condenses and is visible under the microscope and the membrane around the nucleus breaks down.
In the prophase stage, what does the chromosomes consist of?
Each chromosome has two chromatids that are held together by a centromere.
What happens during the metaphase stage of mitosis?
Chromosomes line up in the middle of the cell with the centromeres being the same distance from each side of the cell.
What happens during the anaphase stage of mitosis?
The chromatids separate and are pulled to opposite sides of the cell, with both sides of the cell having a complete set of chromosomes.
What happens during the telophase stage of mitosis?
During this last phase of mitosis, a new nuclear membrane forms around each group of chromosomes.
What happens after mitosis?
After mitosis, cytokinesis results in two new cells and both new cells start the cycle again.
Homologous chromosomes
Chromosomes that are found in pairs that have the same structure and size.
