Unformatted text preview: like rRNA or finally coding for a protein). The gene includes, however, regions preceding and following the coding region (5' UTR and 3' UTR) as well as (in eukaryotes) intervening sequences (introns) between individual coding segments (exons).” non-coding is introns and coding sequences are exons and the introns are revmoed during RNA processes But what we would really like to know is everything: “The ultimate goal of sequence annotation is to arrive at a complete functional description of all genes of an organism. However, function is an ill–defined concept. Thus, the simplified idea of “one gene – one protein – one structure – one function” cannot take into account proteins that have multiple functions depending on context (e.g., subcellular location and the presence of cofactors)….” (* see supplemental info) 5 BIO 1140 Unit 2-2: Transcription At the level of the genome, is the genome what we think it is? Most of the genome in “higher eukaryotes” consists of repeated sequences & mobile elements called tra...
