1. Identify the most ACCURATE description of what happens during Mitosis.
A parent cell's genome is split in half between two daughter nuclei.
A parent cell's genome is replicated and then divided between two daughter cells.
Identical copies of chromosomes are separated into two daughter nuclei.
One cell divides to yield two haploid identical cells.
The genetic contents of one cell are passed on to two new offspring.
2. If each of our cells contain the SAME genome, how is it possible for specialized cells to produce different proteins?
All cells express the same genes, but the final proteins are modified after translation.
Cell cycle controls are turned on or off.
Different genes are replicated during Interphase.
Different sets of stem cells are expressed.
Different subsets of genes are transcribed and then translated.
3. Identify the TRUE statements about STEM CELLS.
Select the TWO answers that apply!
All types of stem cells can indefinitely renew themselves.
Progenitor cells are capable of self-renewal and are less specialized than stem cells.
Stem cells are undifferentiated, unlike the other mature cells in your body.
Stem cells have different subsets of genes than the rest of your cells.
Stem cells have a wide range of developmental fates.
When conducting research on stem cells, scientists can only use cells from an embryo.
4. If you have the SAME protein-encoding genes as your mother, why do some of your phenotypes DIFFER?
Different subsets of genes are expressed between the two of you.
Only the dominant phenotypes are expressed.
Your father's phenotypes are stronger than your mother's.
Your genes have different levels of expression.
You have different allele combinations (or genotypes) than your mother.
5. If homologous chromosomes pair up instead of aligning in a single-file line down the equator during Mitosis, WHEN did an error occur?
Anaphase.
Cytokinesis.
Interphase.
Metaphase.
Prophase.
Telophase.
6. If a cell lacks centrioles and microtubules, the spindle cannot form. WHEN did an error occur?
Anaphase.
Cytokinesis.
Interphase.
Metaphase.
Prophase.
Telophase.
