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.

c.) In the oxygen cycle; contributes to the removal of H2O2 formed in the oxidation of glycolate by O2

i) Takes place in Peroxisome

ii) In Mitochondria

iii) In the Chloroplasts

In Glycolate pathway, Glycine exits the peroxisomes and enters the mitochondria where a multienzyme complex catalyzes the conversion of two molecules of glycine and one molecule of NAD+ into one molecule each of serine, NADH, NH4 +, and CO2; the enzyme complex used in this reaction is
