Narrative:

We were cleared to descend and maintain 11000 ft. Approach control pointed out traffic for us, an medium large transport in a departure climb with a restriction to maintain 10000 ft. The medium large transport was at our 12 O'clock position and opposite direction. We called the traffic in sight. A few seconds later, the TCASII gave a TA 'traffic, climb.' the captain was the flying pilot and started an immediate climb. This action took us to 11800 ft. Traffic passed without further incident and the ATC facility was advised of our climb. Approach was continued to dfw for a landing on runway 35R. The captain was the PF. Dfw tower vectored us in on a close-in right base leg to runway 35R. Once on the base leg, tower asked if we had the field in sight. The copilot confirmed with the captain that she had the field in sight, and she called yes 'field in sight.' tower cleared us for the visual approach. At this point, both the first officer and myself told her she needed to start the turn to final. She must have misidented runway 35R and overshot final. The overshoot carried us as far as the final approach to runway 35L. Tower was advised of the deviation. Correction was made without any traffic incursion, and landing on 35R was completed.
