Some mutations in the bacterial lacI gene can cause its product to behave in a “dominant” manner, whereby the phenotype associated with a given lacI allele cannot be fully rescued by the addition of a normal lacI allele on an artificial chromosome. Which of the following is a feature of LacI that allows these mutations to function in a dominant fashion?

You are researching regulation of the head gene, and are designing an experiment to test whether the magenta enhancer (“E” near the head gene) ~~~~~~~~~~~~~   What is the expected morphological output of these new mutations (red ovals)? [Your answer should be ~10 words or fewer, >20 words results in -0.5]

You must first answer the online quiz questions, to get credit for completing the questions. For full credit, i.e., to show your work, you must upload your handwritten work (can be electronic/tablet handwritten work or scanned handwritten work on paper). Save or scan all of your handwritten work into ONE pdf file and upload it to this question. If you are using Honorlock, it will flag that you used your phone, but we can match the time stamp of the flag to the submission time of your quiz or exam.

Consider a transmitter that uses the following protocol. The “N out of K” code, where N bits must be a “1” and K-N bits must be a “0” where N=3 and K=7. Define error detection failure for this code.   Answer format: Only type your answer in the answer box to this question. Do not handwrite your answer to this question.

Note: To complete this quiz: First work out the answers handwritten on paper or handwritten on a tablet screen. This way, if something goes wrong with your Internet connection, you will still have your answers available to turn in. Second, enter your answers to the questions in the quiz, as this is your answer sheet for completing the questions. Third, in the last question of the quiz, you must upload a scan of your handwritten work.  

True or False? If transmission channels become virtually error-free, the data link layer will no longer be needed. In the next question you must provide 1-3 sentences to explain your answer.

Consider the figure and assumptions in the image for the ARQ problem. Suppose there are no errors. What is the maximum possible window size, Wmax (in number of frames), that can be used for the proper exchange of frames between Node A and Node B? Assume the frames have a 2-bit sequence number, i.e., the frames are counted as follows: F00, F01, F10, F11, F00, F01, F10, F11, etc. If you cannot determine the maximum window, just write Wmax = 2 as your answer. Points for wrong W will be deducted only for this question. Answer Format Wmax = [maxframes] frames (Integer)  

Which encoding scheme, Manchester encoding or the MLT-3 encoding shown on the formula sheet, is the best for i) clock recovery, ii) dc offset, iii) reduced baud rate? In the next question you must provide 1-2 sentences each to explain your answer.  Answer format: For each block, type Manchester or MLT-3 i) The best for clock recovery is [clock]  ii) The best for DC offset is [dcoffset] iii) The best for reduced baud rate is [baudrate]
