Textbook Question
Chapter 17, Problem 10TY
Why do cells within an organism differentiate, such that one cell may eventually become a liver cell and another will become an epithelial cell?
a. Cells differentiate because of differences in gene expression.
b. Cells differentiate because different genes within them encode for different proteins.
c. Cells differentiate because of crossing-over, a random process.
d. Cells differentiate because of differences in genetic code.

What is the purpose of mitosis?
a
It ensures that new nuclei have an exact copy of DNA.
b
It ensures the reproduction of mitochondria and chloroplasts.
c
It guarantees that each daughter cell has half the amount of DNA of parent cells.
d
It prevents the occurrence of cancer cells.
Which process leads to independent assortment?
a)The process of separating chromosomes
b)The random alignment of homologs with respect to the others on the metaphase plate
c)The process of forming the mitotic spindle

- (short answer) Imagine you’ve been offered a deal from a genomics company. You can get a free genome sequence – an analysis of all of your DNA that includes a report of your ancestry, traits and a medical profile. The medical profile tells you about diseases for which you have a low risk of getting, and also those you have a high risk of getting. Are you interested? Why or why not?arrow_forwardCompare the amount of DNA at the beginning & at the end of S (synthesis). Any changes to the set of DNA? A. Because the cell has divided and there is now twice as many chromosomes B. the chromosomes make copies of themselves, so the number doubles C. DNA gets split, so there is 1/2 the amount available D. DNA gets copied, so the cell now contains twice the amount of DNA.arrow_forwardExplain why the recessive white eye gene in male fruit flies can disappear in one generation and show up in another.
