What defines the end of a eukaryotic gene?

▸ A 3' UTR of at least 25 nucleotides recruits an RNase that cleaves the pre-mRNA.

▸ There is no clearly defined end to eukaryotic genes, unlike for bacterial genes.

▸ A stem-loop structure in the transcriptional terminator region stalls the RNA polymerase.

▸ Presence of a stop codon leads to RNA polymerase stalling and ceasing transcription.

▸ Presence of a polyadenylation signal sequence leads to cleavage of the pre-mRNA.
You have been assigned to test the hypothesis that the median number of cars waiting in line for the drive-thru window during lunch hour differs between Chick-fil-A, Wendy's, and McDonald's. The following data show the number of cars in line during randomly selected times during the lunch hour at all three chains.



Perform this hypothesis test using α = 0.05.

Hooke's law is applicable to idealized (linear) springs that are not stretched or compressed too far. Consider a nonlinear spring whose restoring force is given by F(x) = 15x - 0.3x3, for |x| ≤ 8. How much work is done in compressing the spring from its equilibrium position (x = 0) to x = -0.5? Round to two decimal places when appropriate.
