In a day deeply affected by the weather, England cashed in on conditions and put India's batsmen to the sword.
Virat Kohli and co will look for early wickets on Saturday as the second England-India Test match enters its third day.
England lead the five-match series 1-0 after their thrilling 31-run win at Edgbaston last weekend.
Presumably wondering whether the ball would have missed leg-stump, Jennings reviewed the decision, only for DRS to show the ball clattering into middle.
Rahane, who did all the hard work to survive 44 deliveries, nicked Anderson's straight delivery to first slip Alastair Cook. England's record run-scorer made a fluent start to his innings but was beaten all ends up by Ishant Sharma and nicked behind.
