The Israeli powered a 90th-minute header past Wojciech Szczesny and then removed his shirt to reveal a picture of his late father Avi, who died in December following a motorcycle accident, before breaking down in tears.
On-loan Chelsea striker Daniel Sturridge had opened the scoring in the 38th minute while Kevin Davies also missed a penalty for Bolton at the start of the second half before Robin van Persie netted a 48th-minute equaliser.
The result leaves Arsenal nine points behind Manchester United and three behind Chelsea with only four games remaining.
