Explain how the double helix structure of DNA and the base paring rules work together to result two identical copies of the original DNA molecule

DNA Structure, Function and Replication. DNA is a long molecule that consists of two strands of nucleotides twisted together in a long spiral called a double helix ... The base-pairing rules describe which bases pair together in a DNA double helix ... work together to produce two identical copies of the original DNA molecule.=DNA Structure; DNA Function; RNA; Replication; Transcription; Translation ... The two strands are wound round each other to form a double helix. The two strands are joined together by hydrogen bonds between the bases ... before every cell division, so that one identical copy can go to each daughter cell.=Because the two strands of a DNA molecule have complementary base pairs, the nucleotide ... each can be used as a pattern or template to produce a complementary strand ... together then form a new DNA double helix, identical to the original ... The enzyme DNA polymerase then moves along the exposed DNA strand
