RT- PCR reverse transcription- polymerase chain reaction)can be used to compare gene expression levels during an organism's response to the environment.A scientist monitoring a tetracycline resistance gene will see what response in the expression when the organism is challenged?
A)increased gene expression
B)no change in gene expression
C)decreased gene expression

Question

Quizplus · Accepted Answer

The tetracycline resistance gene is likely to be upregulated or have increased gene expression when the organism is challenged with tetracycline. This is because the gene is involved in resistance to the antibiotic and the organism will need to increase its expression to survive the challenge. Therefore, the best choice is A - increased gene expression.
