Topoisomerases (red) reduce torsional strain caused by the unwinding of the DNA double helix; DNA helicase (yellow) breaks hydrogen bonds between complementary base-pairs; single-strand binding proteins (SSBs) stabilize the separated strands and prevent them from rejoining .
Of course, the best course of action is to <u>re-analyze</u> the samples again and generate a new dataset. This would be time consuming and may require further cost. But this would be the best possibility to eliminate bias from the data.
In case, if re-analysis is not possible, then another option is to see the standard deviation among replicate. If only one replicate is contaminated, and other two are fine, then we can simply remove the contaminated sample considering it as an outlier.
The claim is that most people of that descion have chosen the race and choice of either stopping or continuing, the claim is that with diagnostic studies diet might be better than normal but has 1000 more fiber than the leading brand. I hoped I helped :)
