And following the additional detachment of this cap the guanacine nucleotide is also altered in several ways. One of the ways in which the guanacinucleotide is altered is by the methylation of the seven position to form the seven methyl guanosine nucleotide. So this type of five guanosine triphosphate cap is shown in the diagram. So let's pretend that this is the five end of our premna that is synthesized directly following the process of transcription. So basically what we do is we add this guanacine nucleotide via the following triphosphate bond. The reason it's called a triphosphate bond or a triphosphate linkage is because we have one, two, three phosphorus atoms.
