How are genes coordinately controlled in eukaryotic cells?

The control of gene expression is more complex in multicellular eukaryotes than in prokaryotes because __________. (Explain your answer.)

a. Eukaryotic cells are much smaller

b. In a multicellular eukaryote, different cells are specialized for different functions

c. Prokaryotes are restricted to stable environments

d. Eukaryotes have fewer genes, so each gene must do several jobs

Predict how a mutation that caused continuous production of active p53 would affect the cell.

Which of the following statements about the DNA in one of your brain cells is true?

a. Most of the DNA codes for protein.

b. The majority of genes are likely to be transcribed.

c. It is the same as the DNA in one of your liver cells.

d. Each gene lies immediately adjacent to an enhancer.

One hypothesis for differences between humans and chimpanzees involves differences in gene regulation. A study using RNA-seq showed that the overall patterns of gene expression were similar in the liver and blood of the two species, but the expression patterns were strikingly different in the brain. How do these results relate to the hypothesis?
