Biologists Examining the Plant Gene LEAFY's Effect on Expression Patterns

Multiple Choice

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 762?

A) Its expression steadily increases as LEAFY expression is increased.
B) Its expression steadily decreases as LEAFY expression is increased.
C) Its expression is highest when LEAFY is normally expressed; its expression substantially decreases as LEAFY is either overexpressed or underexpressed.
D) Its expression is lowest when LEAFY is normally expressed; its expression substantially increases as LEAFY is either overexpressed or underexpressed.
E) LEAFY has little or no effect on its expression.
