Choose the THREE most correct statements regarding interpretation of the gene expression microarray data shown above.

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.
