principle of error-prone PCR???

... as combine with the regulatory subunit to control the activity, or something else. I mean, it is obviously not the charges, Mn2+ ions carry two positive as well as magesium; plus, Mn2+ ions have exactly the same function with Mg2+, to active enzymes.

Graphs depicting qPCR fold change

... it is harder to appreciate the extent of down-regulation. 2. Using inverse values where negative values (<-1) represent down-regulation and positive values (>+1) represent up-regulation. However, the problem with this approach is that a fold change of +1 is essentially equal to -1, and ...
