"a single gene produces two different proteins, utilizing different exons. produce the explanation"

Explanation:

Exons can be shuffled  independently known as exon shuffling. It can be done in various ways, leading to infinite number of combinations to discover new and meaningful coding sequences hence various proteins. Due to exon shuffling, evolution need not  occur only by the slow accumulation of point mutations but  might also move ahead by “quantum leaps” with new proteins  appearing in a single generation.
