Which of the following statements describes the correlation between the genotype, phosphate concentration, and YJL213W expression based on the data? A - In RM genotypes, a lower PHO4 activation level led to less YJL213W expression and a lower rate of phosphate transport.   B - In RM genotypes, a greater PHO4 activation level led to less YJL213W expression and a lower rate of phosphate transport.   C = In BY genotypes

Question

Scientists studied gene expression and phenotypes of the YJL213W gene in yeast to determine how phosphate was transported based on two different genotypes. The PHO84 locus of the gene is a phosphate transporter and the PHO4 locus is a regulator of genes that respond to phosphate availability.

Two genotypes were compared and are shown in the graph: BY (solid black line, triangles) and RM (dashed line, Xs).

 

Which of the following statements describes the correlation between the genotype, phosphate concentration, and YJL213W expression based on the data?

A - In RM genotypes, a lower PHO4 activation level led to less YJL213W expression and a lower rate of phosphate transport.
 
B - In RM genotypes, a greater PHO4 activation level led to less YJL213W expression and a lower rate of phosphate transport.
 
C = In BY genotypes, a lower activation level of PHO4 led to more YJL213W expression and a higher rate of phosphate transport. 
 
D - In BY genotypes a greater activation level of PHO4 led to more YJL213W expression and a higher rate of phosphate transport.
