Question

Quizplus · Accepted Answer

A library of cloned sequences representing the expressed genes of an organism is known as a cDNA library. cDNA (complementary DNA) is synthesized from mRNA, which only includes the coding regions of genes that are actually expressed by the organism, so it represents the expressed genes only. FISH (fluorescence in situ hybridization) library refers to a collection of labeled DNA probes used for the FISH technique. Gene library and cDNA library are often used interchangeably, but gene library can technically include non-expressed or non-coding regions. Microarray and DNA fingerprint are not relevant to this question.
