To Test for Gene Expression Patterns in Different Tissue Types $\bullet$

question 54

Short Answer

To test for gene expression patterns in different tissue types, mRNA is prepared from mouse cells that are precursors to skin cells and from mouse cells that are precursors to red blood cells. The mRNA from each cell type is converted to cDNA and hybridized to a microarray. Spots containing unique sequences from five genes of the microarray are shown in the following diagram. Color them in as specified.
$\bullet$ Vertical stripes for hybridization to skin cell cDNA only
$\bullet$ Horizontal stripes for hybridization to red blood cell cDNA only
$\bullet$ Filled in completely for hybridization to both cDNA types
$\bullet$ Blank for hybridization to neither skin nor red blood cell cDNA
