In the yeast cross of ade2 met14 his3 x + + +, a total of 120 tetrads are analyzed. The following tetrad types are found in the numbers shown below each tetrad. The markers ade2, met14, and his3 are abbreviated a, m, and h and the wild type allele of each gene is indicated by +.
Use this categorization and the numbers of each type to determine which (if any) of the three markers are linked. For any linked markers, calculate the distance between them in cM.
To measure the distance between two linked His– mutations, you cross a his2– mutant to a his4– mutant and then dissect 100 tetrads. Your lab partner records which spore clones are His+ and which are His– ; but then the fool loses the papers on which most of the data is recorded. In the end all he can remember is that there were three different tetrad types an that there was only one tetrad of the type with 2 His+ and 2 His– spore clones.

The correct order for molecular chaperone–mediated protein folding is:
I – exchange of ATP for ADP on chaperone
II – chaperone undergoes conformational change, which affects protein folding
III – chaperone binds to exposed hydrophobic residues on unfolded protein
IV – folded protein is released

A number of convenient vector systems that incorporate both transcriptional and translational signals for the expression of cloned eukaryotic genes in E. coli have been developed. One such system is called expression vector is
