WebFirst, Nirenberg synthesized an mRNA molecule consisting only of the nucleotide uracil (called poly-U). When he added poly-U mRNA to the cell-free system, he found that the polypeptides made consisted exclusively of the amino acid phenylalanine. WebDuring the process of transcription —which occurs in the nucleus—an mRNA molecule is created by reading the DNA. Note that DNA never “becomes” RNA; rather, the DNA is “read” to make an RNA molecule. The mRNA leaves the nucleus and then, through the process of translation, the mRNA is read to create an amino acid sequence that folds …
