I found the exercise on the internet. Attached is a picture of the <span>statements and the bins.
Operon is not transcribed:
-trp operon: tryptophan present (tryptophan works as an inhibitor of the operon)
-lac operon: lactose absent (lactose works as the trigger for the operon)
Operon is transcribed but not sped up by positive control:
-trp operon: tryptophan absent </span>(tryptophan works as an inhibitor of the operon, when absent the operon is active)
-lac operon: lactose present, glucose present (lactose works as the trigger for the operon, but when glucose is present, the operon activity remains only at basal level)<span>
Operon is transcribed quickly by positive control:
-lac operon: lactose present, glucose absent </span>(lactose works as the trigger for the operon, but when glucose is absent, the operon activity is at its maximum activity)
Upto 50%of human conceptions fail before the little guys can swim successfulllyinto the egg and be home free :)
The answer is D. Bacteria are used to make virus vaccines
The most important mineralocorticoid regulator of electrolyte concentrations in extracellular fluids is Aldosterone.
Aldosterone hormone is produced by the adrenal gland, it acts in the functional unit of the kidneys to aid in the conservation of sodium, secretion of potassium, water retention and to stabilize blood pressure. The hormone causes water to be absorbed along with sodium ions which increases the blood volume and therefore blood pressure. It indirectly regulates blood levels of electrolytes and helps to maintain the blood pH.
