Today's goal: Demonstrate mastery of PCR, restriction enzymes, gel electrophoresis, and microarrays on the methods quiz.
What a finished product looks like
This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.
I reviewed my PCR diagram, gel interpretation, and method comparison, then took the methods quiz.
Correction note for the item I was unsure about: The question asked which method to use to confirm the size of a single amplified fragment. I first picked microarray, but the correct method is gel electrophoresis, because a gel separates fragments by size and a microarray measures expression across many genes, not fragment size.
What I learned: I now match the question to the output. One gene's fragment size means PCR then gel; many genes' expression means microarray.
Also due today: Submit the quiz and your correction note to the course shell.
