    Biology Is a smeared band on a Western Blot a valid result?

    From this result, the conclusion is that MDCK-siNGT and MDCK-siB4Gal4 resulted in less keratin sulfate, while MDCK-RCA did not produce keratin sulfate at all. Looking at the gel, the band look very smeared, as if nothing was purified prior to blotting. I have noticed a similar looking gel in...

    Biology Huntington Disease Pedigree Problem

    The first picture is the image given in the question, and the second picture is the possible genotypes given in the solution manual. How is it possible that person II.1 (first male in the second generation) has the genotype A/- when he is unaffected? I thought that because person II.1 and...

    Finding potential at a point in capacitor

    I tried solving the part (a), and got I =1.82 A for the current value using Kirchoff's law. Next, I want to use Ohm's law to calculate the voltage at point a. Va = IR In this equation, will resistance R correspond to 4.4Ω or 8.8Ω? How do you determine which resistance to use when solving this...

    Using Kirchhoff's Rule - Theory question

    So if you are looking, for instance, Req in circuit a, would it be possible to do so solely using the series/parallel simplification?

    Using Kirchhoff's Rule - Theory question

    Thank you for your reply. But why doesn't the series/parallel rule work for circuit a?

    Using Kirchhoff's Rule - Theory question

    In my lecture, it was explained that Kirchhoff's Rule is used when circuits are too "complicated" to simplify by combining resistances in series and parallel. I do not understand in which cases I can simplify circuits by combining resistances, and on which cases I can only use Kirchoff's Rule...

    Why is it important to classify circuits as series or parallel?

    The answer sheet assumes that the resistors in both circuits are in series and that we need to use the equation Req = R1+R2+R3.. to find the Req in both cases. How come the resistors are in series, when there are multiple resistors in a single row? Also, why does the following work yield the...

    Minimizing the voltage drop across a capacitor (solution shown)

    The following is the question and the solution to the question. I understand the solution to the part where you find the Ceq and derive Qeq from the equation Q = Ceq*V. However, I do not understand where V1 = V0-V2 come from. When calculating the minimum voltage, how do you come up with the...

    Comp Sci Learn How to Write Pseudocode: Questions Answered!

    I just learned about pseudocode, and I am confused about how I should use/write it. For the question, 1: sum ← 0 2: For i in range (3) do: 3: sum ← sum +max(A) 4: remove max(A) from list A 5: return sum The following is the kind of pseudocode I want to write. I have several...

    Determining if a series converges

    The following is my attempt at the solution. Here, I used limit comparison test to arrive at the answer that the series converges. However, the answer sheet reads that the series diverges. I am confused because I cannot figure where my work went wrong… can anyone tell me how the series...

    Using comparison tests and limit comparison test

    The answer sheet states that the series converges by limit comparison test (the second way). In the case of this particular problem, would it be also okay to use the comparison test, as shown above? (The first way) Thank you!

    Questions Regarding Methods of Gene Cloning

    I have been told that the traditional restriction digestion cloning method, where you use restriction enzyme to produce sticky ends in the gene of interest and the plasmid vector, is vulnerable to contamination. The lecturer proceeds to conclude that Gibson Assembly Cloning is therefore a...
