RNA samples are extracted from leaf tissue and root tissue of a plant. Both samples are treated with reverse transcriptase and the resulting cDNA are labelled with different fluorescent compounds (leaf RNA = green, root RNA=red). The labelled cDNA are used to probe a microarray carrying gene segments for a multitude of genes. The results of this experiment are in the table below. The signal level indicates the amount of labelled cDNA of a particular color that has hybridized to that gene spot. Which of the following statements are correct regarding the interpretation of this data? Which of the following statements are correct regarding the interpretation of this data? Tubulin is expressed at equal levels in the cells of the leaf and the root. Genes with a green/red ratio above 1.0 are transcribed at a higher rate in the root tissue. The gene coding for the pollen coat protein is not transcribed in either tissue. Asparagine synthase is expressed at a higher rate in the cells of the leaf. Genes with a green/red ratio above 1.0 are transcribed at a higher rate in leaf tissue. Expression of cytochrome oxidase is only important in the cells of the leaf.
