3000 bp 2500 bp 2000 bp 1500 bp 1000 bp 500 bp B) Your friend notices that Bat 2 is carrying 3 viruses, but only has two bands on the gel. Have you made a mistake, or is there some other explanation? (1 mark) C) A few weeks later, you get some more bat saliva samples to test. You get your samples prepared, load the gel, and run it. After the gel is complete, you realize you forgot to load the DNA ladder. Why is this problematic (2 marks)? D) Two different viral RNA polymerase genes are the same size (both 1000 bp in length) but contain different sequences of nucleotides. Can you distinguish between the two of them if they are both run on the gel but in different lanes, side by side (1) mark)?
