Biologists examining the plant gene LEAFY's effect on expression patterns of genes overexpressed and underexpressed LEAFY.They then performed microarray analysis to examine the effects of changes of LEAFY expression on the expression of other genes in the genome.Refer to the table showing the results for four different genes with LEAFY underexpressed and overexpressed, and the control.The expression levels are normalized such that they are 100 for each gene in control conditions. Which pattern is exhibited by gene 4419?
A) As expression of LEAFY increases, the expression of gene 4419 also increases.
B) As expression of LEAFY increases, the expression of gene 4419 decreases readily.
C) Gene 4419 is most expressed when LEAFY is normally expressed; its expression decreases as LEAFY is either overexpressed or underexpressed.
D) Gene 4419 is least expressed when LEAFY is normally expressed; its expression increases as LEAFY is either overexpressed or underexpressed.
E) LEAFY has little or no effect on its expression.
