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. http://www.yeastgenome.org/cgi-bin/locus.fpl?locus=YPR155C
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.
