There have been various advances in the technology in the last few decades. As the technology has improved, the various fields that are related to it including genetics has also improved. The role and the use of technology in the field of genetics has been amazing to say the least.
The latest trend is the one in which the human genome sequencing is being tried. There have been several successes in the past, where the genes of various animals and organisms have been successfully sequenced. A few of the major successes have been the gene mapping of round worm and the fruit fly. It is being said that the human genes are also very similar to that of the other animals. In fact scientists say that the genes of the mice and the genes of the humans are very similar.
The genome sequencing or the complete gene mapping for humans involves the process in which all the genes are mapped. This will help a lot in the process of research. There are many situations where the people who suffer from certain diseases pass on the disease to the future generations. The role of genetics is to try and prevent the genes from transferring the diseases from one person to the offspring.
Other than the prevention of such diseases being carried, the role of genetics is also present in the treatment of such diseases by methods like gene therapy where a transgene is transferred to the diseased person. This transferred gene will overcome the disease that is present. All these are possible mainly because of the mapping of the genes. The human genome sequencing is a very tough job because of the thousands of genes that are present, which can cause changes in the traits of a person. In fact, there seems to be about 38,000 genes that need to be sequenced.
