Carefully selecting seeds for planting the next year, preventing a weak bull from breeding, and so on, are common and old practices. They lead to the improvement of the gene pool. With the increase in the knowledge of molecular biology, and the decoding of the human genome for example, new tools are being introduced. It is now possible to carefully select a gene in the genome of an individual, and insert it in the genome of another, enabling this transfered gene to be expressed.
You might need to go back to some of the preceding chapters to have a clearer idea.
In this chapter on the Applications of Molecular Biology, some of the basic techniques used in any molecular biology laboratory are presented. The techniques are sorted under the heading 'Genetic mapping', as most of them are used in an attempt to map genes!
Another section, under the heading 'Gene cloning technology', deals with the recombination of DNA, i.e. the use of bacteria, or other organisms, to produce DNA.
In conclusion, a chapter is devoted to some examples of the use of these technologies in real life experiments.
