Rod-shaped structures made of DNA and proteins.
Proteins the DNA in eukaryotic cells wrap tightly around.
Each half of a chromosome.
Point at which the two chromatids of a chromosome attach.
The less tightly coiled DNA-protein complex.
Chromosomes that determine the sex of an organism, and they may also carry gens for other characteristics.
All of the other chromosomes in an organism.
The two copies of each autosome.
Photomicrograph of the chromosomes in a normal dividing cell found in a human.
Cells having two sets of chromosomes.
Cells that contain only one set of chromosomes.
Division of a prokaryotic cell into two offspring cells.
Results in new cells with genetic material that is identical to the genetic material of the original cell.
Production of offspring from one parent.
Occurs during the formation of gametes.
Haploid reproductive cells.
The time between cell divisions.
Division of the cell's cytoplasm.
Phase where the copied DNA coils into chromosomes.
Made of microtubules radiate from the centrosomes in preparation for metaphase.
Phase where the chromosomes line up along the midline of the dividing cell.
Phase where the chromatids of each chromosome begin moving toward opposite poles of the cell.
Phase where the chromosomes reach opposite poles of the cell, and a cleavage furrow is formed.
Vesicles from the Golgi apparatus join together at the midline of the dividing cell to form this.
The pairing of homologous chromosomes, which does not occur in mitosis.
Each pair of homologous chromosomes.
Process where portions of chromatids may break off and attach to adjacent chromatids on the homologous chromosome.
A new mixture of genetic material is created.
Random separation of the homologous chromosomes.
The production of sperm cells.
The production of mature egg cells, or ova.
The three other products of meiosis.
Production of offspring through meiosis and the union of a sperm and an egg.
