DNA is like the instruction manual for building and operating a cell.
Before a cell divides, its DNA is replicated (duplicated.) Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner.
Because it contains the genetic information of every organism
Explanation:
DNA (deoxyribonucleic acid) is the hereditary material mainly located in the cell's nucleus, therefore the DNA's replication is the basis for biological inheritance.
