WebEukaryotic pre-mRNAs must have their ends modified, by addition of a 5' cap (at the beginning) and 3' poly-A tail (at the end). Many eukaryotic pre-mRNAs undergo splicing. In this process, parts of the pre-mRNA (called introns) are chopped out, and the remaining pieces (called exons) are stuck back together. WebThe promoter o f a gene may be defined as the non-coding DNA responsible for direction o f transcription (Figure 1.4). Control o f transcription is mediated by the binding o f transcription factors to specific cw-regulatory elements within the promoter.
