Preview:
One of the specific proteins that regulate the cell cycle.
A. Nucleosome
B. Chromatin
C. Cyclin-dependent kinase
D. Cyclin
Relaxed form of DNA in the nucleus of a cell.
A. Chromatin
B. Chromosome
C. Nucleosome
D. Cytokinesis
Uncontrolled growth and division of cells that can be caused by changes in control of the cell cycle and also may be caused by environmental factors.
A. Cyclin-dependent kinase
B. Cyclin
C. Cancer
D. Carcinogen
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
Protective cap made of DNA that is found on the ends of a chromosome.
A. Centromere
B. Telomere
C. Nondisjunction
D. Cellular Differentation
Second stage of mitosis in which motor proteins pull sister chromatids to the cells equator.
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
Chromosome that is not a sex chromosome.
A. Autosome
B. Gamete
C. Allele
D. Telomere
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
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
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
First stage of mitosis, during which the cell’s chromatin condenses into chromosomes.
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
X or Y chromosome
A. Gene
B. Haploid
C. Autosome
D. Sex Chromosome
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
Programmed cell death
A. Cyclin
B. Cyclin-dependent kinase
C. Apoptosis
D. Cytokinesis
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
