DA replication is initiated at discrete sequences called origin (ori) of replication to which DNA polymerase and accessory proteins bind and copy both strands, as predicted by the semi-conservative replication model (Fig. 2B). In contrast to unidirectional RNA synthesis, DNA replication in most genomes occurs bidirectionally (Fig. 2B). This results in both continuous and discontinuous synthesis of the same strand on two sides of the origin of replication. Some circular genomes, such as mitochondrial DNA, are replicated unidirectionally. In these cases, replication starting at the ori proceeds continuously in the 5′ ^ 3′ direction, followed by discontinuous synthesis of the complementary strand. Termination occurs at the same site as the ori after the circle is completely traversed. During replication of the mitochondrial genome, elongation of the continuous strand pauses at some distance from the ori, resulting in a bubble (6 structure) structure named a D-(displacement) loop (Fig. 4A).

From DNA to RNA to protein, how does it work?
: Bacteria are found almost everywhere on Earth, including in the seas and lakes, on all continents (including Antarctica), in the , and in tissues of plants and animals.

Thus, the genetic code is determined by specific nuleotide basesequences in chromosomal DNA; the amino acid sequence in a proteindetermines the properties and function of the protein; and sequence ofsugars in bacterial lipopolysaccharides determines unique cell wallproperties for pathogens. The primary structure of amacromolecule will drive its function, and differences withinthe primary structure of biological macromoleculesaccounts for the immense diversity of life
