Question

9. You LOVE spinach. This morning you heard on the news that E.coli O157:H7 has contaminated 90% of the spinach crops in your area. E.coli O157:H7 is a pathogenic strain of bacteria that has acquired a gene that produces a toxin that gives people hemorrhagic diarrhea. You are bummed because you CAN’T live without your spinach! You recently began working in a lab that has a PCR machine that you can use. Explain how you could use PCR to determine if the spinach you have is infected with E.coli O157:H7 or not. (3 pts)

Step 1

First, we need to know the specific DNA sequence of the Ecoli 0157:H7 strain that is unique to this strain and not found in other Ecoli strains. This can be done by comparing the genomes of different Ecoli strains and identifying a unique gene or DNA sequence Show more…
