Doesn't a microarray experiment tell us exactly the same thing as an RNA-Seq experiment?
A) Yes
B) Yes, but one technique doesn’t give us any indication regarding the amount of a given transcript
C) Yes, but one technique doesn’t tell us much about mRNA processing
D) No, they are completely different experiments
Correct answer is : B.Yes, but one technique doesn’t give us any indication regarding the amount of a given transcript.
Reason: The difference between RNA-Seq and microarrays is that RNA seq allows for full sequencing of the whole transcriptome while microarray allows for sequencing of only predefined transcripts/genes through the process of hybridization.Also, in microarray getting the amount of transcripts /transcript copy number information is a problem but in RNA-seq,there is high sensitivity of for genes that are either expressed in low or high amounts.
