A) RT-PCR
B) differential display PCR
C) DNA sequencing
D) random PCR
E) library screening

Question

Quizplus · Accepted Answer

Differential display PCR is a method used to compare DNA or RNA samples from different organisms to identify differences in gene expression. It is a technique that amplifies differentially expressed genes, allowing researchers to isolate and identify genes that are up-regulated or down-regulated in one organism compared to another. RT-PCR is a technique used to measure gene expression levels, DNA sequencing is used to determine the sequence of nucleotides in a DNA molecule, random PCR is a technique used to amplify DNA sequences without prior knowledge, and library screening is a method of identifying genes of interest by screening a genomic or cDNA library.
