A 1 ml sample of culture liquid contained 1000 viable bacterial cells. You serially diluted it twice, performing 10-fold or 1/10
Semmy [17]

Answer:

there are 10 viable bacterial cells in 1 ml in the 1/100 dilution tube

Explanation:

in 1ml there is 1000 viable bacterial cells → diluted with 9 ml of solvent (10 ml in total)→  1000 viable bacterial cells in 10 ml (fist tube)

now we take 1 ml of the first tube into the second empty tube → has 1000/10 = 100 viable bacterial cells on 1 ml → diluted with 9 ml of solvent (10 ml in total)→  100 viable bacterial cells in 10 ml (second tube)

then we take 1 ml of the second tube into the third empty tube → has 100/10 = 10 viable bacterial cells in 1 ml → diluted with 9 ml of solvent (10 ml in total)→  10 viable bacterial cells in 10 ml (third  tube)

therefore there are 10 viable bacterial cells in 1 ml in the 1/100 dilution tube

We used the enzyme, taq polymerase, which is derived from the thermus aquaticus bacterium, in our pcr procedure. Why is this enz
Gala2k [10]

Taq polymerase enzyme important for efficiency in PCR because it is thermostable polymerases that remain active at high temperatures (90 -95  degree Celsius) a beyond the denaturation temperature of DNA.

PCR :

Polymerase chain reaction (PCR) is a laboratory technique for rapidly amplifying millions to billions of copies of a specific segment of DNA, which can then be used for further research.

Taq polymerase is a DNA polymerase derived from bacteria called Thermus aquaticus, which are naturally thermophilic and is a thermostable polymerases that remain active at temperatures higher than the temperature at which DNA is denatured. This allows PCR to be used on DNA samples without the need to add new DNA polymerases after each cycle.
