Pval and AvgLogFC Questions

Keeping the "Pval" filter at p < 0.05, filter the "AvgLogFC" column to show all genes with an average log fold change greater than zero. How many meet these two criteria?

Questions

Which gene has the smallest p value in your dataset (at any timepoint)?

  • YPR15SC
  • Protein involved in regulation of mitochondrial expression of subunits 6 (Atp6p) and 8 (Atp8p) of the Fo-F1 ATP synthase; functions with Nca3p. [1]

Why do you think the cell is changing this gene's expression upon cold shock? Involved some way in metabolism response to external temperature change.
