In Autism Spectrum associated Fragile-X disorder disorder, a disease state arises when a CGG repeat located in the 5’ untranslated region of the FMR1 gene is expanded to have up to several hundred copies. The gene is X-linked and about twice as prevalent in males as in females. Given your knowledge of molecular genetics overall, what is a plausible explanation for the effect of repeat expansion on gene function? Increased likelihood of inversions forming between the 5’ UTR and GC rich promoter elements of the 3’ UTR Reduced proofreading by DNA polymerase alpha in CGG-rich domains Enhanced recruitment of DNA methyl transferase leading to DNA methylation and transcriptional silencing A longer Arg-rich domain (encoded by CGG) leads to a highly basic protein and cellular toxicity the X-linked The gene is recessive in males but dominant in females

[18 pts.] Pacemakers, which are devices designed to regulate heartbeats, typically produce square waveforms to stimulate heart tissue. These electrical pulses help manage irregular heart rhythms. Calculate the Fourier Transform of the square waveform defined below, and determine the first three Fourier series components using analytical methods. $x(t) = \begin{cases} 1 & 0 \le t < \frac{1}{2}T_0 \\ 0 & \frac{1}{2}T_0 \le t < T_0 \end{cases}$ for $T_0 = 0.04$ sec.

A new diet is being tested. The inventor claims people lose 10 pounds on average after 6 weeks. 25 people are randomly picked to try the diet. Researchers are concerned the inventor's claim is exaggerated. The sample yields an average of 1.9 and a standard deviation of 6. Calculate the appropriate test statistic. Enter with 2 decimals (eg. 1.96). Question 21 3 pts A new diet is being tested. The inventor claims people lose 10 pounds on average after 6 weeks. 25 people are randomly picked to try the diet.

Question 3. For this question you need to work with text. Write a function that takes in a two text files: one is a book, another file has names in it. You need to determine the 3 most popular names in the book (from the given name list). To do this, implement two helper methods, name_count and make_tuple, that will assist you in finding the answer. def name_count (file, name): Function returns the number of names in file that match the given name. >>> name_count("little_women.txt", "Jo") 1543 >>> name_count("little_women.txt", "Meg") 685 >>> name_count("little_women.txt", "Troll") 0 # YOUR CODE HERE # def make_tuple (name, freq): Function returns a tuple of two inputs. >>> make_tuple (5, 3) (5, 3) >>> make_tuple (2, 2) (2, 2) >>> make_tuple ('red', 5) ('red', 5) #YOUR CODE HERE def three most common names (text, text_names): Function that takes in text (a book) and text names (characters from the book). You must implement this function to find the three most common names in the book. >>> three most common names ("little_women.txt", "names.txt") ['Jo', 'Meg', 'Amy'] # YOUR CODE HERE #
