摘要: Relatively few (2–5%) of the genes in budding yeast Saccharomyces cerevisiae contain introns. Those that do usually only one and this is located close to 5’ end transcript. The MATal RPL8A are exceptions, having two Nevertheless splicing an essential process yeast, as introns occur many genes, including more than 50% ribosomal protein genes. Yeast differ from those higher eukaryotes, not exceeding a hundred nucleotides length, containing highly conserved sequence elements at branchpoint (for review see ref. 1). Despite these differences there considerable evidence mechanism pre-mRNA conserved.
