Cellular and Sexual Reproduction Quiz
Preview:
Cell structure that joins two sister chromatids.
A. Telomere
B. Centromere
C. Chromosome
D. Chromatin
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
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
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
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
Structure that contains identical DNA copies and is formed during DNA replication.
A. Sister Chromatid
B. Chromatin
C. Chromosome
D. Cytokinesis
Programmed cell death
A. Cyclin
B. Cyclin-dependent kinase
C. Apoptosis
D. Cytokinesis
Cell with half the number of chromosomes (n)
A. Haploid
B. Diploid
First stage of mitosis, during which the cell’s chromatin condenses into chromosomes.
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
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
Third stage of mitosis in which sister chromatids are pulled apart and microtubules, along with motor proteins, move the chromosomes to opposite poles of the cell.
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
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
A haploid sex cell, formed during meiosis, that can combine with another haploid sex cell and produce a diploid fertilized egg.
A. Autosome
B. Sex Chromosome
C. Gamete
D. Gene
Process of cellular reproduction that occurs in three stages.
A. Mitosis
B. Meiosis
C. Cell Cycle
One of the specific proteins that regulate the cell cycle.
A. Nucleosome
B. Chromatin
C. Cyclin-dependent kinase
D. Cyclin
Micrograph in which the pairs of homologous chromosomes are arranged in decreasing size.
A. Gene
B. Gamete
C. Crossing Over
D. Karyotype
Chromosome that is not a sex chromosome.

Second stage of mitosis in which motor proteins pull sister chromatids to the cells equator.
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
