Final answer:

The triplet corresponding to ACG on the coding strand of DNA on the template strand is TGC, adhering to the base pairing rules where A pairs with T and C pairs with G.

Step-by-step explanation:

The complementary pairing of nucleotides in DNA is governed by the principle of base complementarity, where adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). This fundamental rule guides the formation of the DNA double helix and is crucial for accurate DNA replication and transcription processes.

If the triplet on the coding strand of DNA is ACG, its complementary triplet on the template strand can be determined by applying the complementarity rule. In this case, adenine (A) on the coding strand pairs with thymine (T) on the template strand, cytosine (C) pairs with guanine (G), and guanine (G) pairs with cytosine (C). Therefore, the corresponding triplet on the template strand is TGC.

Moreover, the antiparallel nature of DNA strands plays a critical role in determining the orientation of base pairs. The template strand is oriented in the 3'-to-5' direction, while the coding strand is oriented in the opposite 5'-to-3' direction. Consequently, when examining the template strand sequence, it reads 5'-TGC-3', which is the antiparallel complement to the coding strand sequence 3'-ACG-5'.

This adherence to base complementarity and the antiparallel arrangement ensures the faithful transmission of genetic information during processes such as DNA replication and transcription, maintaining the integrity and accuracy of the genetic code in living organisms.
