The correct answer is: MAO inhibitors.
MAOI - monoamine oxidase inhibitors are antidepressants that affect the enzyme called monoamine oxidase which normally removes the neurotransmitters norepinephrine, serotonin and dopamine from the brain. As a consequence, neurotransmitter’s activity is increased. MAOIs interact with tyramine, amino acid found in food such as cheese, smoked sausage, and red wine. Tyramin eis normally regulated via MAO. So, when the MAO is inhibited via MAOI, tyramine reaches high levels, causing the blood vessels to narrow and resulting in critically high blood pressure.
Answer: A. sorE encodes a gene that increases I. hockious virulence
Explanation:
Notice that at the start of the study, there were 10 times mutant gene lacking sorE compared to the wild type. After 24 hours, it reduced to 5 times compared to the wild type, this is an indication that sorE is a virulence gene and it's absence reduces the virulence of the bacteria.
I believe that the reason for using taq polymerase for pcr is that; it is heat stable and can withstand the temperature changes of the cycler. Taq polymerase is isolated from a heat loving bacterium that is naturally found in hot springs, so the enzyme doesn't break down at the high temperatures necessary for copying DNA using a polymerase chain reaction. At high temperatures, Taq polymerase attaches nucleotides to a DNA template, thereby copying the DNA.
