A. Cyclin
B. Cyclin-dependent kinase

A. Fertilization
B. Nondisjunction
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 with half the number of chromosomes (n)
A. Haploid
B. Diploid
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
Repeating subunit of chromatin fibers, consisting of DNA coiled around histones.
A. Chromatin
B. Chromosome
C. Nucleosome
D. Cell Cycle
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
Programmed cell death
A. Cyclin
B. Cyclin-dependent kinase
C. Apoptosis
D. Cytokinesis
Structure that contains identical DNA copies and is formed during DNA replication.
A. Sister Chromatid
B. Chromatin
C. Chromosome
D. Cytokinesis
Chromosome that is not a sex chromosome.
A. Autosome
B. Gamete
C. Allele
D. Telomere
Third stage of the cell cycle, during which the cell’s cytoplasm divides, creating a new cell.
A. Cell Differentation
B. Telomere
C. Centromere
D. Cytokinesis
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
Second stage of mitosis in which motor proteins pull sister chromatids to the cells equator.
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
Reduction division process, occurring only in reproductive cells, in which one diploid (2n) cell produces four haploid (n) cells that are not genetically identical.
A. Nondisjunction
B. Cellular Differentiation
C. Meiosis
D. Mitosis
One of the specific proteins that regulate the cell cycle.
A. Nucleosome
B. Chromatin
C. Cyclin-dependent kinase
D. Cyclin
Having two copies of each chromosomes (2n)
A. Haploid
B. Diploid
Micrograph in which the pairs of homologous chromosomes are arranged in decreasing size.
A. Gene
B. Gamete
C. Crossing Over
D. Karyotype
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. Telomere
First stage of mitosis, during which the cell’s chromatin condenses into chromosomes.
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
DNA-containing structure that carried genetic material from one generation to another.
A. Chromatin
B. Chromosome
C. Nucleosome
D. Gene
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
