Ch. 11: Cell Division - Answer
Ploidy - Answer -Designated as the letter "n"
-Human's ploidy is 22 --> 23 pairs of chromosomes
Diploid cells - Answer -2n
-2 sets of genomes
Examples of diploid cells - Answer -Somatic cells- body cells that make up tissues and organs
-Zygotes-results from fusion of 2 haploid gametes
Haploid cells - Answer -"n"
-One set of genome
Example of haploid cells - Answer Gametes
Chromosomes - Answer -Sister chromatids (both from mom)
-Share same centromere
-Share same genetic info
Non-sister chromatids - Answer -One is mom, one is dad
-DO NOT share same centromere
-DO NOT share same genetic info
What do non-sister chromatids do that sister chromatids do not do? (Hint: another word for
recombination) - Answer Crossing over
When do sister chromatids separate? - Answer During Mitosis and Meiosis II
Homologs/Homologous chromosomes - Answer DO NOT share centromeres/same genetic
info
, Phases of Mitosis - Answer -Prophase
-ProMetaphase
-Metaphase
-Anaphase
-Telophase
Prophase - Answer -Chromatin condenses and chromosomes become visible
-Centromere splits, begins to move to opposite ends of cell
-Mitotic spindles begin to form
-Nuclear envelope breaks down
Prometaphase - Answer Spindles attach to chromosomes at kinetochore
Metaphase - Answer Chromosomes align at center of the cell
Anaphase - Answer -Sister chromatids are separated at the centromere and move towards
opposite ends of the cell
-Occurs because of dynamic instability in microtubules
**Spindles are still present!!**
Telophase - Answer -Nuclear envelope begins to reform
-Spindles begin to break down
-Chromosomes begin to de-condense and become chromatin again
-Cell prepares for cytokinesis
Phases of Meiosis I - Answer -Prophase I
-Metaphase I
-Anaphase I
-Telophase I
Prophase I - Answer -Chromosomes become visible
-Homologous chromosomes continue to condense and undergo synapsis (gene for gene pairing)
Metaphase I - Answer -Homologous pairs line up at the center of the cell
