Create a multitape turing machine with Two tapes, each tape represents a side of the

double helix strand of DNA. There are four bases$--$adenine $($A$),$ cytosine $($C$),$ guanine $($G$),$

or thymine $(T.$ The alphabet is therefore $A,C,G,T.$ Adenine forms a base pair with thymine,

and cytosine forming a base pair with guanine. Your machine should process the two input

strings. If every pair at the identical position is one of the accepted pairs, continue, if you find

an incorrect base pair, $($e$.$g$.$ tape $0$: T and tape $1$: G is incorrect$)$ delete the pair then shift the

characters to eliminate the resulting space, rewind and start again. The final result contains

only correct base pairs, remember it might be $A$ on tape $0,T$ on tape $1$ or $T$ on tape $0$ ande $A$

on tape $1$
