Gene Expression
... RNA polymerase transcribes both the exons and introns, producing a long RNA molecule. Enzymes in the nucleus then add further nucleotides at the beginning (cap) and end (tail) of the RNA transcript. Other enzymes cut out the RNA introns and splice together the exons to form the true mRNA, which move ...
