The precursor of egp is translated from a transcript that has had one nontemplated 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:
amino-terminal sequence as sgp, but a different primary carboxy-terminal sequence
carboxy-terminal sequences as sgp, but different primary amino-terminal sequence
sequence as sgp except egp has one additional aa
sequence has sgp except that egp has one less aa

Step-by-step explanation:

As you can observe in the image attached, the graphed system has a unique solution.

Remember that a system can have one solution, infinite many solutions or none. Where the lines intersect, they would do it in one point only, because they are straight line, in that case we say that the system has a unique solution.

Additionally, where the system is about two parallel lines one on top of the other, we say that the system has infinite many solutions. And, where the lines are parallel each other and not on top, we say the system doesn't have a solution.

Therefore, the right answer is one.
