Microarrays are often used to monitor the RNA level of a large number of genes in an organism or cell type under different environmental conditions. In recent years the value of these microarrays has come into question because there is often not a good correlation between the level of functional protein and the level of mRNA for all genes. Which of the following is NOT a reason for this lack of correlation? ● A. RNAs can be degraded at different rates. B. Not all mRNAs are efficiently translated. XOC. Codon bias can play a role in translation of each mRNA. D. Nuclear export is important in gene expression. OE. Splicing is not accounted for by many microarrays. Answer Key: A
