E Correct answer
Explanation

All are incorrect, hence this is correct answer. DNA microarrays are used to measure the concentration of different mRNAs in a biological sample. The complete set of mRNAs that are transcribed in a cell is often called its transcriptome. Expressed sequence tags (ESTs) are short, single-read cDNA sequences.
