The number of strands and the AWG of a strand are separated by a slash. He wears a simple single strand of beads. I posed with a strand of imitation pearls. It then produces an RNA chain, which is complementary to the template DNA strand. A wire is a single, usually cylindrical, flexible strand or rod of metal. A polymerase sequences the complementary strand on top of the arched strand. DNA replication occurs on multiple origins of replication along the DNA template strand. DNA replication on the lagging strand is discontinuous. These wires are neighbours along the whole length of the strand. Recombination allows alleles on the same strand of DNA to become separated. The interaction is crucial in creating proper ligation of the lagging DNA strand. PCR amplifies a specific region of a DNA strand (the DNA target). Bleomycin acts by induction of DNA strand breaks. Blond hair is the result of having little pigmentation in the hair strand. This is because adenine introduced into the new DNA strand is unmethylated.
