It initially created many more jobs, by enhancing worker productivity through the use of technology (from an electric drill, to a calculator). As technology progressed the tools became more powerful, and it then became more efficient to use more capital and less labour in these industries.
CH 9 1. When a DNA molecule doubles, a chromosome is then made up of two joined _______. Answer: chromatids 2. Prokaryotic DNA molecules are packaged by _______ proteins, which associate with DNA. Answer: basic 3. In general, the division of the cell, called _______, follows immediately upon mitosis.
DNA replication is the action of DNA polymerases synthesizing a DNA strand complementary to the original template strand. To synthesize DNA, the double-stranded DNA is unwound by DNA helicases ahead of polymerases, forming a replication fork containing two single-stranded templates.Replication processes permit the copying of a single DNA double helix into two DNA helices, which are divided into the daughter cells at mitosis.nitiation of eukaryotic DNA replication is the first stage of DNA synthesis where the DNA double helix is unwound and an initial priming event by DNA polymerase Î± occurs on the leading strand. The priming event on the lagging strand establishes a replication fork.
