RNA serves as a template for cDNA synthesis. In cellular life, cDNA is generated by viruses and retrotransposons for integration of RNA into target genomic DNA. In molecular biology, RNA is purified from source material after genomic DNA, proteins and other cellular components are removed. cDNA is then synthesized through in vitro reverse transcription. RNA is transcribed from genomic DNA in host cells and is extracted by first lysing cells then purifyi… WebThis primer consists of a 15-mer oligonucleotide that shows thymidine (T) at each individual position.
