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 funcution; 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 divison, so that one identical copy can go to each daughter cell =because the two strands of a DNA molcule 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 orginal. The enzyme DNA polymerase then moves along the exposed DNA strand
