Final answer:
It is important for both copies of the DNA produced by DNA replication to have the exact same sequence of nucleotides as the original DNA because each strand serves as a template for the synthesis of a complementary strand. This ensures that the genetic information is accurately passed on to the daughter cells.
Step-by-step explanation:
During DNA replication, each of the two strands that make up the double helix serves as a template from which new strands are copied. The new strands will be complementary to the parental or 'old' strands. When two daughter DNA copies are formed, they have the same sequence and are divided equally into the two daughter cells.
