The current status of cDNA cloning.
The cloning of cDNAs, copies of cellular RNA, is one of the classical technologies in molecular biology. Over the past 30 years cDNA cloning technologies have been improved to enable the cloning of large cDNA collections, which are fundamental to today's understanding of the utilization of genetic information. With the discovery of noncoding RNAs, additional new approaches to the cloning of short RNAs have been developed. However, with the realization that much larger portions of genomes are transcribed than anticipated from genome annotations, cDNA cloning faces new challenges to uncover rare transcripts and to make the corresponding cDNAs available for functional studies. This review provides an overview on the current status of cDNA cloning and possibilities for the discovery and characterization of new RNA families.
