Question 1058057: The half-life of messenger RNA (mRNA) in the cytoplasm of a bacterial cell is approximately 3.3 minutes. Assuming continuous decay, if 3000 mRNA molecules are produced in a bacterial cell before synthesis is suddenly halted, how long will it take for only 100 molecules to remain?

:
Use the decay formula; A = Ao*2(-t/h), where:
A = Amt remaining after t time (100)
Ao = Initial amt (3000 ml)
t = time of decay
h = half-life of substance (3.3 min)
:
3000*2^(-t/3.3) = 100
2^(-t/3.3) = 100/3000
2^(-t/3.3) = 1/30
Using nat logs ln(2) = *.693 = -3.401 = = -4.907
t = -4.907 * -3.3
t = +16.2 min to decay to 100 molecules
