Haploid	Diploid	Centromere	Autosome	Chromosome
Describes a cell, nucleus, or organism that has only one set of unpaired chromosomes.	A cell that contains two haploid sets of chromosomes.	The region of the chromosome that holds the two sister chromatids together during mitosis.	Any chromosome that is not a sex 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.

Homologous chromosomes	Karyotype	Zygote	DNA Replication	Chromatid
Chromosomes that have the same sequence of genes, that have the same structure, and that pair during meiosis.	An array of the chromosomes found in an individual’s cells at metaphase of mitosis and arranged in homologous pairs and in order of diminishing size.	The cell that results from the fusion of gametes; a fertilized egg.	The process of making a copy of DNA.	Half of a chromosome when it is in the duplicated form.

Mitosis	Prophase	Metaphase	Telophase	Anaphase
In eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes.	The part of mitosis where chromosomes coil up and the nuclear envelope dissolves.	The part of mitosis where duplicated chromosomes line up at the equator of the cell.	The part of mitosis where a nuclear envelope forms around the chromosomes at each pole.	The part of mitosis where spindle fibers shorten and pull sister chromatids toward opposite poles of the cell.

Interphase	Cytokinesis	Meiosis	Gamete	Mutation
A period between two mitotic divisions where the cell grows, copies DNA and synthesizes proteins.	The part of mitosis where the cytoplasm is divided.	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.	A haploid reproductive cell that unites with another haploid reproductive cell to form a zygote.	A change in the nucleotide-base sequence of a gene or DNA molecule

Synthesis	Protein	Ribosome	Nucleus
The putting together of parts to form a whole	An organic compound made of amino acids	A cell organelle composed of RNA and protein; the site of protein synthesis	In a eukaryotic cell, a membrane-bound organelle that contains the cell’s DNA and that has a role in processes such as growth, metabolism, and reproduction
