Examine the Following Two DNA Sequences

Examine the following two DNA sequences. Sequence 1: ATGCGATGCTAGCAT
Sequence 2: ATGCGATGATAGCAT
If both of these sequences code for proteins, how might the function of protein 2 differ from the function of protein 1? Use the genetic code below for assistance.

A) Protein 1 and protein 2 will function exactly the same.
B) Protein 1 will be shorter than protein 2, so they will not function the same.
C) Protein 2 will be shorter than protein 1, so they will not function the same.
D) Protein 2 has a different sequence, so it will function differently from protein 1.
