D. Cyclin
Process by which haploid gametes combine, forming a diploid cell with 2n chromosomes, with n chromosomes from the female parent and n chromosomes from the male parent.
A. Fertilization
B. Nondisjunction
C. Cellular Differentiation
D. Meiosis
DNA-containing structure that carried genetic material from one generation to another.
A. Chromatin
B. Chromosome
C. Nucleosome
D. Gene
Last stage of mitosis in which nucleoli reappear. Two new nuclear membranes begin to form, but the cell has not yet completely divided.
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
The process by which an unspecialized cell develops into a specialized cell with a defined structure and function.
A. Gene
B. Autosome
C. Nondisjunction
D. Cellular Differentiation
When homologous chromosome pairs align on the spindle during metaphase I the orientation of one pair is independent of the orientation of any other pair.
A. Fertilization
B. Independent Assortment
C. Cellular Differentiation
D. Meiosis
Unspecialized cell that can develop into a specialized cell under the right conditions.
A. Haploid
B. Diploid
C. Allele
D. Stem Cell
Cell structure that joins two sister chromatids.
A. Telomere
B. Centromere
C. Chromosome
D. Chromatin
Cell with half the number of chromosomes (n)
A. Haploid
B. Diploid
Enzyme to which cyclin binds during interphase and mitosis, triggering and controlling activities during the cell cycle.
A. Cyclin
B. Cyclin-dependent kinase
C. Chromatin
D. Chromosome
Second stage of mitosis in which motor proteins pull sister chromatids to the cells equator.
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
Functional unit that controls inherited trait expression that is passed on from one generation to another generation.
A. Gene
B. Gamete
C. Homologous Chromosomes
D. Autosome
Second main stage of the cell cycle during which the cell’s replicated DNA divides and two genetically identical diploid daughter cells are produced.
A. Mitosis
B. Meiosis
C. Cellular Differentiation
D. Nondisjunction
One of the two paired chromosomes, one from each parent, that carries genes for a specific trait at the same location.
A. Gene
B. Homologous Chromosome
C. Gamete
D. Sex Chromosome
Cell division in which the sister chromatids do not separate correctly, resulting in gametes with an abnormal number of chromosomes.
A. Cellular Differentiation
B. Nondisjunction
C. Crossing Over

D. Gene
Micrograph in which the pairs of homologous chromosomes are arranged in decreasing size.
A. Gene
B. Gamete
C. Crossing Over
D. Karyotype
Structure made of spindle fibers, centrioles, and aster fibers that is involved in moving and organizing chromosomes before the cell divides.
A. Centromere
B. Telomere
C. Spindle Apparatus
D. Chromosome
