Features of the genetic code
... • A capping enzyme adds a G to the first nucleotide in the transcript in the unusual 5’-5’ direction (phosphate to phosphate bond). Then a methyl thransferase adds methyl groups (-CH3) to the G and one or more of the first few bases of the RNA transcript. Capping and methylation is believed to be cr ...
