1. The following R code sorts each vector in a list (lst) and stores the new list in lst1. The code uses a for loop.

   lst <- list(c1=sample(1:10,10,replace=TRUE),c2=sample(1:20,10,replace=TRUE),c3=sample(1:10,8,replace=TRUE))
   lst1 <- list()
   for(i in 1:length(lst))
   {
   lst1[[i]] <- sort(lst[[i]])
   }
   lst1

   Which of the following options does the same thing as the given R code above ?

   		lst <- list(c1=sample(1:10,10,replace=TRUE),c2=sample(1:20,10,replace=TRUE),c3=sample(1:10,8,replace=TRUE)) library(purrr) lst1 <- map(lst,sort) lst1
   		lst <- list(c1=sample(1:10,10,replace=TRUE),c2=sample(1:20,10,replace=TRUE),c3=sample(1:10,8,replace=TRUE)) library(purrr) lst1 <- map_dbl(lst,sort) lst1
   		None of the given options
   		lst <- list(c1=sample(1:10,10,replace=TRUE),c2=sample(1:20,10,replace=TRUE),c3=sample(1:10,8,replace=TRUE)) library(purrr) lst1 <- map_int(lst,sort) lst1

QUESTION 4

1. The following R code extracts the unique items in each vector in a list (lst) and stores the new list in lst1. The code uses a for loop.

   lst <- list(c1=sample(1:10,10,replace=TRUE),c2=sample(1:20,10,replace=TRUE),c3=sample(1:10,8,replace=TRUE))
   lst1 <- list()
   for(i in 1:length(lst))
   {
   lst1[[i]] <- unique(lst[[i]])
   }
   lst1

   Which of the following options does the same thing as the given R code above ?

   		lst <- list(c1=sample(1:10,10,replace=TRUE),c2=sample(1:20,10,replace=TRUE),c3=sample(1:10,8,replace=TRUE)) library(purrr) lst1 <- map_int(lst,unique) lst1

3. You are working with wild-type cells that have a 16h doubling time. BrdU is a molecule that can be used to measure the amount of DNA inside cells. When added to cell culture, cells will incorporate BrdU into DNA strands during replication as if it were the DNA base thymidine (T).

Your general experiment for using BrdU is:
1. Add BrdU to the media and let the cells continue to grow for 16h
2. Harvest cells and label them with a fluorescent antibody against BrdU
3. Measure fluorescence intensity in cells which is proportional to total DNA content
4. Plot a histogram which shows the number of cells with a certain fluorescence intensity

A. (5pts) As a control, you perform the above experiment on normally growing, wild-type cells, and find the histogram to the right. Please explain why one peak shows roughly twice the fluorescence intensity as the other, what sets cells are represented by each peak, AND why the high-intensity peak is smaller.

PART B:

B. (5pts) You perform the general experiment with the following addition: when you add BrdU, you also add the drug taxol, which stabilizes microtubules. You find the histogram to the right. Please describe how the features of this histogram have changed from Part A, and explain why adding taxol could cause these changes referring to mechanisms we have discussed in class.

PART C:

C. (4pts) You construct a cell line with a temperature sensitive mutant of the G1-cyclin. You perform the general experiment with the following additions: when you add BrdU, you shift to higher temperatures, which deactivates the G1-cyclin. Please draw what you predict will be the resulting histogram after you measure BrdU on the figure to the right.

(Note: The result from the control is printed as a reference, you should draw your response on the same axes.)

Write a program that sorts prices of 10 tacos in ascending order based on the price, using arrays.

Requirements:

• The user enters the name of the taco and then the price of the taco
  • HINT: Two arrays make this problem simpler. One with the names and the other with the prices. The indices indicate the combination. For instance, a taco price at index 5 has its name also at index 5 of the other array.
  • HINT: It is a good idea that after using keyboard.nextDouble() to write the following line: keyboard.nextLine();. The scanner will not consume everything in the buffer unless you tell it to using nextLine.
• After 10 tacos are entered they are sorted based on the price
  • You can use any sorting method such as bubble sort or selection sort
• Display the results at the end
• Arrays must be part of the solution, and other built in Java data structures, such as ArrayLists, may not be used.
• Sorting must be implemented (bubble sort, selection sort, etc.) in the solution, and other built in Java sorters may not be used.

The user inputs the students first name and last names separately but within one loop. The loop should end when the user presses enter on the first name without entering any text. Upon completing entry of data, the output pictured above should display on the output.

Using the code given, follow the steps:

1. You should be able to enter up to 20 student first names. Also, change the input array to an appropriate size of 18 for the length of the first name. Use a meaningful name for the storage of first names array. Change prompts as needed. The loop should exit when the user presses enter when inputing the first name without adding any text. Compile and make sure it works from main(). At this point, you should be able to enter and alphabetize a list of up to 20 first names! Alphabetizing the first name is just a test!!! In the end, you will alphabetize the whole name string.

2. Add another array and get input for last name INSIDE the loop for your first names. This last name array will also be an array of 20 elements but with room for up to 25 characters. Again, do not use another loop! Just add code to input the last name to the first loop. The program should now ask the user to input the student's first name and then last name in that order for each individual. Then the program will loop to continue adding student names until the user presses enter on the student's first name. Make sure the last name is converted to all caps. You do not need to alphabetize this array, but you may want to print it out to make sure everything is working just as a test.

3. Make changes to convert the first name to all upper case using a function. (Example: User enters bob on the first name, then on the last name enters jenkins, it will look like Bob Jenkins instead of bob jenkins)

Last step: Combine last and first into an third array. This code is most easily added to the first loop. You just had the user enter first and last names. So the current value of the subscript used for these arrays can be used to combine content and store in the third array.  Alphabetize THIS array (instead of the first name array) which means you need to send a different pointer to the stsrt() function. Print out the end result. Test that everything is working on this program.

Given Code:

void rollsheet(void) {
int ct = 0;
char *ptstr[LIMIT];
char input[LIMIT][SIZE];
int k;

printf("Enter up to %d student names, and I will sort them!\n", LIMIT);
printf("To stop, press the Enter key at a line's start.\n");
while (ct < LIMIT && s_gets(input[ct], SIZE) != NULL
&& input[ct][0] != '\0')
{
ptstr[ct] = input[ct]; /* set ptrs to strings */
ct++;
}
stsrt(ptstr,ct);
puts("\nHere's the sorted list:\n");
for (k = 0; k < ct; k++)
puts(ptstr[k]) ; /* sorted pointers */
}

for (top = 0; top < num-1; top++)
for (seek = top + 1; seek < num; seek++)
if (strcmp(strings[top],strings[seek]) > 0)
