Nitrogenous Base Pairing Rules

In this engaging exercise, students will explore the fundamental nitrogenous base pairing rules of DNA and RNA, discovering how adenine pairs with thymine (or uracil in RNA) and cytosine pairs with guanine, through interactive activities and visual aids that illustrate the significance of these pairings in genetic coding and replication.
