Dining Space Tips. 1  Use a rug to define a dining area in an open floor plan. 2  Here, an old-fashioned farmhouse-style table and distressed chairs keep the dining room's look relaxed.
In summary, DNA replication is the process of making copies of DNA. DNA replicates by semi-conservative replication, which means that one strand of the parent double helix is conserved in each new DNA molecule. Meselson and Stahl were the scientists who showed that DNA follows the semi-conservative model.
B. DNA Replication in Bacteria. DNA Replication in Bacteria. In general, DNA is replicated by uncoiling of the helix, strand separation by breaking of the hydrogen bonds between the complementary strands, and synthesis of two new strands by complementary base pairing. Replication begins at a specific site in the DNA called the origin of replication (oriC). DNA replication is bidirectional from the origin of replication. To begin DNA replication, unwinding enzymes called DNA helicases cause short segments of the two parent DNA strands to unwind and separate from one another at the origin of replication to form two Y-shaped replication forks. These replication forks are the actual site of DNA copying (see Fig. 4).
