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.
Transcription. Transcription is a process that involves the transcribing of genetic information from DNA to RNA. There are three main steps to the process of transcription. First, DNA is transcribed by an enzyme called RNA polymerase. Specific nucleotide sequences tell RNA polymerase where to begin and where to end.here are three primary types of RNA involved in protein synthesis: messenger RNA, transfer RNA and ribosomal RNA. Messenger RNA. Whereas most types of RNA are the final products of their genes, messenger RNA (mRNA) is an intermediate in the information transfer process.
