  1. There are total 864 (3 × 6 × 4 × 6 × 2 = 864) possible DNA sequences created by combining codons from each position. Any combination, for example ATTCGTGGTCGTGAA, or the original sequence, ATCCGTGGGCGTGAG, can be translated to the same amino acid sequence IRGRE. The brute force approach is not practical because of the exponential growth in the number of possible sequences.
