The term intron refers to both the DNA sequence within a gene and the corresponding sequence in the unprocessed RNA transcript. As part of the RNA processing pathway, introns are removed by RNA splicing either shortly after or concurrent with transcription. Introns are found in the genes of most organisms and many viruses.
To obtain eukaryotic cDNA whose introns have been removed: 1  A eukaryotic cell transcribes the DNA (from genes) into RNA (pre-mRNA). 2  The same cell processes the pre-mRNA strands by removing introns, and adding a poly-A tail and 5â Methyl-Guanine cap (this is known as post-transcriptional modification)
