Question

one strand of a dna molecule has the sequence atgctga. what is the corresponding sequence on the second strand? tacgact cgtagtc atgctga gcatcag

Explanation:

DNA follows base-pairing rules: A pairs with T, G pairs with C. For the strand ATGCTGA, each base is replaced by its complement: A→T, T→A, G→C, C→G, T→A, G→C, A→T. This gives TACGACT.

Answer:

TACGACT
