The last letter is A.

Each set of letters correspond to numbers in base 4.

T = 0

A = 1

G = 2

C = 3

When converted to base ten, the pattern is as follows:

12345

23456

34567

45678

56789

The last pattern in base 4 is 31313111, which is represented by C A C A C A A A.

Notice these has nothing to do with biochemistry?Just look like it. Obviously there is no pattern at all. They cant represent words.

The last letter is A. Yes it is

Each set of letters correspond to numbers in base 4.

OP say "basic"

number system doesnt begin in 0

and since ascending in sequence ,you got the key here

T = 0

A = 1

G = 2

C = 3

When converted to base ten, the pattern is as follows:

Internet converter base 4 to base10 is easier to use

12345

23456

34567

45678

56789

The last pattern in base 4 is 31313111, which is represented by C A C A C A A A. Good solving!
