The Turing machine performs all of the mentioned functions after reading a symbol. It can move the tape one cell to the left or right, write a symbol, and proceed with the next instruction or halt. Therefore, the answer is "none of the mentioned".

The Turing machine performs all of the following functions after reading a symbol:

1. Moves the tape one cell left or right.
2. Writes the symbol.
3. Proceeds with the next instruction or halts.

Therefore, the answer to your question is "none of the mentioned". There are no functions listed that the Turing machine does not perform after reading a symbol.
