A 10-7 is performed on a culture of bacteria in order to perform viable plate counts. From the dilution, *0.1 mL* of solution is

marishachu [46]

Answer:

$66 * 10^8$ CFU/mL

Explanation:

Given -

a) Number of colonies of bacteria is equal to $66$

b) Total volume of the solution is equal to $0.1$ mL

c) Dilution factor is equal to $10^{-7}$

As we know that

CFU/mL $= \frac{N * DF}{V}$

Where N is the number of bacterial colonies, DF is the dilution factor and V is the volume

Substituting the given values in above equation, we get -

CFU/mL $= \frac{66* 10^7}{0.1} \\= 66*10^8$

Substitution mutation

kicyunya [14]

Substitution mutation is when a single base pair in a strand of DNA is replaced. This can cause an early stop amino acid, or the protein could change slightly, or the protein could be unchanged completely due to there being multiple base pairs to make an amino acid.
