predict the effect of a mutation that prevents the expression of aurka on a normal (noncancerous) cell
earnstyle [38]

Answer:

Nowadays, if a cell cannot express the AURKA gene, malignant neoplasms or cellular malignancies can be generated.

since it is related to the KRAS gene.

There is some scientific evidence or research that maintains that FOSL1 acts on another gene, AURKA, whose expression to date was thought to be independently regulated by the KRAS oncogene, and for which clinical trials are currently underway with a drug that inhibits it. .

Explanation:

Aurora kinase A also known as serine / threonine-protein kinase 6 is an enzyme that in humans is encoded by the AURKA gene.

Under normal conditions, what would be the PRIMARY mechanism that his body would use to reduce the amount of PCO2 in the blood
sergeinik [125]

The pH of blood if pco2 drops to 35.0 mmHg is 7.459

The pH of the blood can be calculated using the Henderson- Hasselbalch equation, which explains the relationship between acid dissociation constant pKa and pH in biological and chemical systems.

pH = pK + log ( HCO3- / ( 0.03 * PCO2 ) )

pK is 6.1 for the bicarbonate buffer system.

HCO3- = 24mm

PCO2  = 35.0 mmhg

pH = 6.1 + log ( 24 / 0.03 * 35.0 )

    = 6.1 + log ( 24 / 1.05 )

    = 6.1 + log 22.8571

    = 6.1 + 1.3590

    = 7.459

Hence, the pH of blood is 7.459
