Quiz 9

Match the step of PCR with what is occurring in the test tube.

Annealing: DNA primers hybridize to the DNA strand Denaturation: Double stranded DNA melts to single stranded DNA Extension: DNA strand elongates with DNA polymerase.

__________ is more resistant than ___________ to processing and can be extracted from highly processed foods, making it a better option for identifying GM in food.

DNA, Proteins

What is the correct order for the steps of PCR amplification ?

Denaturation, Annealing, Extension

What is the test that can be used to detect proteins that are produced in GM crops?

ELISA
