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.
Figure 1. Before a cell divides, its DNA is replicated (duplicated.) Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner.f the two strands of a DNA molecule are separated, each can be used as a pattern or template to produce a complementary strand. Each template and its new complement together then form a new DNA double helix, identical to the original.
