Let's say we have 2 bases, and the original sequence is AA. Then the list of sequences accessible by a single point mutation is (AT, AG, AC, TA, GA, CA). That's six, which is 3*2, not 3^2.
If we have three bases, starting from AAA, we get (AAT, AAG, AAC, ATA, AGA, ACA, TAA, GAA, CAA). That's 3*3 = 9, not 3^3 = 27. And so on. You do know * is a multiplication sign, right?

Oh, brother.
Dan, Dan, Dan...
"AAA" doesn't equal 3 base pairs. "AA" does not equal 2 base pairs.
So you got the biology wrong. Then after listing "AA" you contracted yourself with "A does not pair with A."
Then you got the math wrong: it's not 3*1953, it's 3^1953.
Congrats. You're 0 for 3.
