Original strand is the old strand and replicated strand is new strand.
Explanation:
DNA is replicated by the semi-conservative way which means the new strand is replicated over the old strand and one DNA duplex has one new strand and one old strand. So the original strand is the old strand and the replicated strand is the strand that is synthesized over the original strand.
In DNA the replicated strand is made by adding nucleotides complementary to the opposite nucleotide present in the template or original strand. Adenine and thymine make complementary base pairing with each other and guanine and cytosine makes complementary base pairing with each other.
