Choose the THREE most correct statements regarding interpretation of the gene expression microarray data shown above. The color code is represented by the following using a reference gene as the control; RED means higher level of gene expression, GREEN means lower level of gene expression, and YELLOW would mean that the expression is unchanged.

Question 6 options:

Genes in the C group are coordinately controlled and display a so-called down-up-down pattern similar to insulin regulation of glucokinase gene expression in pancreatic cells. 

Genes in the A and D groups are differentially expressed at the same level as the control genes during the early time course, but have equivalent expression later in the time course.

Genes in the D group are initially expressed at the same level as the control genes, but have increased expression later in the time course.

Genes in the B group are the only genes that display differential gene expression as a function of time, the other gene groups show differential gene expression as a function of the evolutionary tree.

Genes in the D group are initially expressed at the same level as the control genes, but have decreased expression later in the time course.

Genes in the A, B, C, and D groups are all on the same chromosome and show a differential pattern of expression over time because of differences in the location of each gene relative to the centromere.

Genes in the A group are initially expressed at the same level as the control genes, but have increased expression later in the time course.

Genes in the B and C groups are differentially expressed at about the same time, but the pattern of expression is reciprocal.
