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.
One chromosome (non-replicated) i.e equal to one chromatid = 1 DNA molecule. One chromosome (replicated) i.e equal to 2 chromatids (aka sister chromatid) = 2 DNA molecules. So, if you are looking up a cell in G1 phase you would effectively have 46 molecules of chromosomal DNA.
