Answer:
In fact, the key difference between "template based" and "template free" structural prediction methods lies in the different conformational initialization methods. Template based prediction method obtains the initial conformation by searching and recognizing the known structure which has homology or structural similarity with the target protein as the template; template free prediction method usually constructs the initial conformation from the beginning with a small structure fragment.
At present, no matter which method is used, the known structural information in PDB database will be used to construct an initial conformation which is far better than random conformation, thus significantly reducing the pressure of conformation search, including reducing the amount of calculation and reducing the dependence on high-precision force field

Answer:
Explanation:
given cells at incubation = 2 million (2 x 10^6) Staph
cells at the start of incubation = 200 Staph
Total time =6hrs = 360minutes
Recalling that Number of generations = Log(cells at incubation) - Log (cells at the start of incubation)/0.301
- Number of generations = Log 2000000 - log 200 /0.301
= 20.93 generations.
- hence generation time = total time/number of generations
= 360/20.93 = 17.20minutes
as said, that the apple pie is left after 2hrs, it implies 8hrs (480minutes) will be the new total time; number of generations = total time / generation time
= 480/17.20minutes = 27.90 generations
- hence total number of bacteria after 8hrs = 2^n generations x initial number of bacteria
= 2^27.90 x 200 staph = 5.009 x 10^10 bacteria
I think the answer is d but I’m not sure
