India still needed 72 more runs but Gill and Jurel rotated the strike to take singles before completing his half-century with two consecutive sixes off Bashir.
Jurel scored the winning run, punched the air and hugged his teammate and the Indian dressing room erupted in celebration.
India made a strong start in the morning with captain Rohit Sharma and Yashasvi Jaiswal taking their opening day partnership of 40 runs to 84 runs.
Root made the breakthrough in his first over of the day when he edged Jaiswal to a diving catch at backward point off James Anderson on 37.
Rohit completed his half-century but was stumped by Ben Foakes on 57 off the left-arm spin of Tom Hartley.
The army of England fans went wild when Bashir, who took his first five-wicket haul in the first innings, had Rajat Patidar caught by Ollie Pope on zero, taking India's score to 100-3.
