Chapter 11 Notes: DNA and Genes
... In transcription, a single strand of mRNA is copied from DNA, by an enzyme called RNA polymerase. In this case, however, thymine is replaced with uracil, so the “new” base pairing rule is C-G & A-U. The mRNA is then able to move through the nuclear membrane into the cytosol. Remember that all RNA i ...
