1 The primer acts as the starting point for DNA synthesis. 2  DNA polymerase binds to the leading strand and then âwalksâ along it, adding new complementary nucleotide bases (A, C, G and T) to the strand of DNA in the 5â to 3â direction. 3  This sort of replication is called continuous.4  Lagging strand: This sort of replication is called continuous. 2  Lagging strand: 3  Numerous RNA primers are made by the primase enzyme and bind at various points along the lagging strand. 4  Chunks of DNA, called Okazaki fragments, are then added to the lagging strand also in the 5â to 3â direction.
Back in Chicago, OKeh Records decided to let Armstrong make his first records with a band under his own name: Louis Armstrong and His Hot Five. From 1925 to 1928, Armstrong made more than 60 records with the Hot Five and, later, the Hot Seven.
