A transformation experiment is carried out using donor DNA that is A+B+C+ and a recipient that is A-B- C-. A+ transformants are selected and tested further. Of these, 64% are B+ and none are C+. Also, B+ are selected, and 8% are also C+. What is the gene order

We need to minimum buffering capacity is required so that the pH value of the samples analyzed does not have any influence on the system, 

What would happen if we used the higher buffering concentration

a) more electric power is applied, resulting in higher heat development. 

b) less electric power for less time  is applied, resulting in very high  heat development

c) higher buffering concentration need more electric power resulting increases in the temperature will increase the mobility and rate of migration of ions.

d) using the higher buffering concentration shows no affect at all
