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.
Definition. In the nucleus, the DNA double helix is packaged by special proteins (histones) to form a complex called chromatin. The chromatin undergoes further condensation to form the chromosome.So while the chromatin is a lower order of DNA organization, chromosomes are the higher order of DNA organization.An organismâs genetic content is counted in terms of the chromosome pairs present. e.g. humans have 23 pairs of chromosomes.hromosomes are formed of compacted chromatin where DNA is condensed at least by 10,000 times onto itself. The major structures in DNA compaction; DNA, the nucleosome, the 10nm beads-on-a-string fibre (chromatin), 30nm fibre (chromatin), and the metaphase chromosomes.
