Effects of water pollution. You will notice in the previous pages that water pollution is very harmful to humans, animals and water life. The effects can be catastrophic, depending on the kind of chemicals, concentrations of the pollutants and where there are polluted. Below, we shall see a summary of the effects of water pollution.
Recombinant DNA is an artificial form of DNA that cannot be found in natural organisms. It is made in the laboratory by joining together genes taken from different sources. This is done by selecting and cutting out a gene at a specific point on a strand of DNA using restriction enzymes which act as molecular scissors.
Recombinant DNA is one of the core techniques of genetic engineering. It is the process of removing DNA from one organism and inserting it into the DNA of another organism, giving it new traits. Recombinant DNA can be used to make crops resistant to pests or disease, it can be used to make livestock leaner or larger.In medicine, the technique can be used to develop drugs, vaccines, and to reproduce important human hormones and proteins.By engineering human DNA into a host organism, that organism can be turned into a factory for important medical products. Insulin production is an excellent example of the recombinant DNA process.n medicine, the technique can be used to develop drugs, vaccines, and to reproduce important human hormones and proteins.
