"WebIn between exons, there are intervening non-coding sequences called introns. This type of genes are called split genes or interrupted genes. They are most common in enkaryotes. They are also found in viruses but rarely in bacteria. The terms exons and intons were given by Gilbert in 1977. " - Introns og exons

WebJan 4, 2015 · Edit: If you're actually starting from a GenBank record, then it's not much harder. Assuming that the full junction string you're looking for is in the CDS feature info, then: for f in record.features: if f.type == 'CDS': jct_info = str (f.location) converts the "location" information into a string and you can continue as below. WebThis gene contains about 186 kb of DNA and is divided into 26 exons. The mRNA is only about 9 kb long, which implies that about 175 kb of the gene contains introns. On average, introns constitute about 10 times more DNA than exons in the genes of higher eukaryotes. Although most eukaryotic genes contain introns, their presence is not universal.
