27. DNA synthesis Suppose that upon synthesizing a molecule of DNA, you introduce a wrong base pair, on average, every 1000 base pairs. Suppose you synthesize a DNA molecule that is 1000 bases long.(a) Calculate and draw a bar graph indicating the yield (probability) of each product DNA, containing 0, 1, 2, and 3 mutations (wrong base pairs).(b) Calculate how many combinations of DNA sequences of 1000 base pairs contain exactly 2 mutant base pairs.(c) What is the probability of having specifically the 500th base pair and the 888th base pair mutated in the pool of DNA that has only two mutations?(d) What is the probability of having two mutations side-by-side in the pool of DNA that has only two mutations?

As per the given information,the probability of introducing a wrong base pair is the probability of…

9 (C) (a) You give your students the following problem: "You just bought 30 beads of which 18 are gold and identical and 12 are silver and identical. You want to line them up in a row. How many different arrangements of the beads can you make?" Elizabeth solves the problem by finding the number of distinguishable permutations of 30 objects, 18 alike of one kind and 12 alike of another kind. That is, she uses the result of the previous problem. Natalie solves the problem by finding the number of combinations of 30 different objects taken 18 at a time. Who is correct? (b) Does the number of permutations of n objects, ralike of one kind and n r alike of another kind, always equal the combinations of n different objects taken r at a time? Explain.

2. Iconic memory is a type of memory that holds visual information for about half a second (0.5 second). To demonstrate this type of memory, participants were shown three rows of four letters for 50 milliseconds. They were then asked to recall as many letters as possible, with a 0-, 0.5-, or 1.0-second delay before responding. Researchers hypothesized that longer delays would result in poorer recall. The number of letters correctly recalled is given in the table for this between-subjects designs. G=114 ΣΧ2 = 878 N=18 0 12 11 6 10 8 7 T = 54 M=9 SS=28 Delay Before Recall (in seconds) 0.5 8 4 10 6 3 5 T = 36 M = 6 SS = 34 1.0 4 b. Compute eta-squared to measure the effect size. WOH 4 2 5 7 2 T=24 M=4 SS = 18 a. Do the data indicate that delay to recall had a significant impact on number of words recalled? Use the hypothesis testing steps & alpha = .05. Compute any necessary post-hoc tests.

You are interested in finding out if kangaroo rats that have been offered food ad lib(unlimited food) for the previous 24 hours store a different amount of food in their pouches than kangaroo rats that have been starved for 24 hours. You take 8 kangaroo rats and starve them for 24 hours, then offer them food and count how many seeds are stored in their pouches in the next hour. You let your rats rest for one week, and repeat the experiment with the same rats, but offer them unlimited food for the 24 hours prior to the experiment. Run the appropriate statistical test.
