The decimal reduction time (DRT) to kill 90% of cell present for autoclaving a culture is 1.5 minutes. How long would it take to kill all the cells if 106 cells were present? What would happen if you stopped the heating process at 9 minutes?
Answer:
10.5minutes
Explanation:
DRT = 90%
Cells present = 10^6
Autoclaving = 1.5 minutes
Solution:
10^6(1.5)10^5(1.5)10^4(1.5)10^3(1.5)10^2(1.5)10^1(1.5)10^0(1.5)0=10.5
it would take it approximately 10.5 minutes to kill 10^6 of the cells.
If i should stop the heating process at 9 minutes this would have effect on some of the microbes as they are still present with 1 bacterium left which makes it not efficient.

Do the same mechanisms that govern gene expression operate in bacterial cells and eukaryotic cells? Explain your answer.
Answer:
in prokaryotic cells, the control of gene expression is mostly at the transcriptional level. ... Eukaryotic gene expression is regulated during transcription and RNA processing, which take place in the nucleus, and during protein translation, which takes place in the cytoplasm.
