If the kinase that adds the inhibitory phosphate to cdk were defective then the M phase would begin prematurely. Of the many proteins involved in cell cycle control, cyclin-dependent kinase (CDKs) are among the most important. They are a family of multifunctional enzymes that can modify various protein substrates involved in cell cycle progression. M-phase promoting Factor is a complex of a cyclin and cyclin dependent kinase that, when activated, phosphorylates a number of specific proteins needed to intiate mitosis in eukaryotic cells. The cyclin sub-unit regulates the formation of the MPF dimer; the kinase subunit catalyzes the phosphoryation of other proteins to start M phase.
I believe it is water depth.
The water depth will tell us the sunlight that the ecosystem gets. I hope this helps! :)
It increases the rate of a chemical reaction.
Answer:
Letter d. Evola virus could not produce an exotoxin
Explanation:
Viruses are acellular particles carrying genetic material only for their reproduction. None of the viruses produces toxins, viruses atack by altering the normal function of the host cell. In the other hand, bacteria involve in alimentary infections like <em>E. coli, S. aureus</em> and <em>C. botulinum</em> produce exotoxins to attack the host cells to colonize and start an infection. The exotoxin is too potent that alter the function of the intestinal cells before the immune system recognize the bacteria.
