Answer:
TCA
Step-by-step explanation:
Deoxyribonucleic acid (DNA) is a molecule composed of two polynucleotide strands that coil to form a double helix structure. These DNA strands are antiparallel (i.e., they run in opposite directions) and complementary because the nucleotide sequence in one DNA strand determines the sequence in the other DNA strand. According to the base pair rules, Adenine (A) always pairs with thymine (T), and Guanine (G) always pairs with Cytosine (C). Therefore, if a DNA strand has the sequence AGT, then the other DNA strand will have the complementary sequence TCA.
