question 163

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 gene(s) is/are most likely inhibited by LEAFY?

• B) Gene 1567 only
• C) Gene 3407 only
• D) Both genes 3407 and 4419
