I have output from ADC as MISO and MOSI, can I use this signals to TX and RX in arduino uno? if not what will the solution for this?
MISO and MOSI are the names of the signals used by the SPI protocol (along with SCK, a clock signal that must be used to synchronize them but which you haven't mentioned), while the Arduino's TX and RX are for a standard (unclocked) serial connection, so are not compatible.

On the Arduino Uno, SPI is usually connected with pins MOSI->11, MISO->12 and SCK->13.  The Arduino library has a class SPI that can be used to control the transfers.  See the documentation here for details.
