E)clone-by-clone sequencing.

Question

Quizplus · Accepted Answer

Microarrays are commonly used to analyze gene expression levels by hybridizing the array with RNA from the tissue of interest, allowing for the identification of genes that are differentially expressed. Probing the array with another DNA sequence or other genetic markers such as SNPs or STSs would not provide the same information about gene expression levels. Clone-by-clone sequencing is also not relevant for microarray analysis.
