The precursor of EGP is translated from a transcript that has had one non templated nucleotide added to the open reading frame. This change does not create or eliminate a stop codon. Compared with the protein sGP, which is produced from the unedited transcript, EGP most likely has the same primary:

Explanation:

It was added somewhere in the middle. Since this is a frameshift, everything downwind of the addition will most likely be different.

The question is basically asking, if you change everything from the middle to the end of an amino acid sequence, which end changes and which end would remain the same?

It basically asks, when amino acids are assembled into proteins, are they built from the amino to the acid direction, or the acid to the amino direction?

The answer is that amino acid sequences are always assembled N to C, much like nucleotide sequences are built 5 to 3.
