The following question refers to the enzyme chymotrypsin.

For an experiment, you are asked to modify the sequence of chymotrypsin so that, it instead of cleaving C-terminal to a Phe/Tyr residue, it cleaves after Lys. Please describe the strategy you would take in your design, considering what you have learned. Please explain with clarity and detail.

A genetic experiment with peas resulted in one sample of offspring that consisted of

440

green peas and

163

yellow peas.

a. Construct a

95​%

confidence interval to estimate of the percentage of yellow peas.

b. It was expected that​ 25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas is not​ 25%, do the results contradict​ expectations?

(3) You have a 5 M sucrose stock solution and need 90 mL of the three following solutions for your experiment: 0.5 M, 0.05 M, and 0.005 M sucrose, respectively. How will you prepare the 3 sucrose solutions you need? You can use a diagram to explain your answer.

Information on a packet of seeds claims that 93% of them will germinate. Of the 220 seeds that I planted, only 187 germinated.

Compute a 95% two-sided Agresti-Coull CI on the proportion of seeds that germinate. Use as a point estimator p^ the proportion of seeds that germinated during the experiment.
Round your answers to two decimal places

Experiment: An urn contains 4 blue marbles and 8 orange marbles. Two marbles are drawn without replacement. What is the probability that a blue and orange marble are drawn? A) 0.4444 B) 0.2424 C) 0.1212 D) 0.4848 E) 0.2222

The answer is D I just don't understand how my professor got it.

In a Compton scattering experiment, a photon with a wavelength ?=1.50x10^-3 nm collide with a stationary electron. After the collision, the electron recoils at 0.500c a) What is the energy and wavelength of the scattered photon? b) through what angle with respect to the incident direction was the photon scattered? [Hint: Me=0.511 MeV/c² or Me=9.11x10-31 kg]

2. Using the Michelson-Morley experiment as an example, explain why classical mechanics was unable to explain natural phenomena.

3. Using at least one of Einstein's "thought-experiments", explain how special relativity addresses how it is possible for observers in two different inertial reference frames to “disagree” about time and distance intervals.

When setting up a PCR experiment, you must prepare a positive control sample. What would the positive control help you discover?

A) You forgot to add Loading Dye to your samples

B) The DNA ladder is denatured

C) Your thermocycler is broken

D) Your reagents are contaminated with foreign DNA

A genetic experiment with peas resulted in one sample of offspring that consisted of 438 green peas and 162 yellow peas. a. Construct a 95​% confidence interval to estimate of the percentage of yellow peas. b. It was expected that​ 25% of the offspring peas would be yellow. Given that the percentage of offspring yellow peas is not​ 25%, do the results contradict​ expectations?

Jenae changed the original coffee labels with plain white ones that had the flavor printed in bold black letters, and she placed them on the coffee pots for the week-long experiment.

Jenae used an aspect of experimental design known as ________ when she created the labels to have the same appearance.

• randomization

• a control

• replication

• a treatment
