. As a matter of fact Genome is the hereditary information of an organism that is encoded in the DNA which includes the genes and other non-coding sequences.
The author is an evolutionist who usesthe genome to support the theory of evolution. The genome, he writes, allows us to see the different changes that our organism experienced since the beginning of our existence until now. But thechapter that interested me the most was chapter 9 dedicated to the disease. I have always wondered what causes diseases in the human being and in this chapter he first explains that “genes are not there tocause diseases”, but there are abnormal genes that were result of a toxic exposure, mutations, diet, environmental effects or unknown reasons that do cause diseases. This helped me understand thecause of diseases that I didn’t understand before. For example hemophilia, a blood clotting disorder, is an X linked disease which means that the disease is inherited from mother to son and there is anabnormal gene on the X chromosome and affects mostly males. Another disease is Cystic fibrosis which is an inherited disease that causes thick, sticky mucus to build up in the lungs and digestivetract. The condition is caused by a defective gene which tells the body to produce abnormally thick and sticky fluid, called mucus. This mucus builds up in the breathing passages of the lungs and thepancreas, the organ that helps to break down and absorb food.
The genome can be used for many things such as determining changes of a specific organism or most important it helps scientists to findbetter treatments or potential cures for terminal diseases such as cancer. The genome shows which genes are activated which genes are shut down or which genes are mutated and with this informationscientists can predict the potential disease in an individual and perhaps find a treatment or cure for the disease being studied. The sequencing of the genome was a breakthrough for medicine, with the...
