Answer: The nucleotides found on the other DNA strand in the 5' to 3' direction are ACT.

Explanation: A DNA has two complementary antiparallel strands in which one strand runs in the 5'->3' direction and the other runs in the 3'->5' direction. If one strand of a DNA has AGT nucleotide sequence in 5'->3' direction, the complementary strand will have TCA nucleotide sequence in 3'->5' direction.

Since the question is the nucleotide sequence of the other strand in the 5'->3' direction, therefore the sequence TCA should be read in reverse order, and that is ACT.
