What is an inherited gene?
Genetic genes, also known as genetic factors, are chemical substances with complex structures that determine the genetic characteristics of organisms. In 1953, American geneticist Watson and British biophysicists Crick and Wilkins discovered that in the 46 chromosomes of human fertilized eggs, chemical substances containing deoxyribonucleic acid (DNA) are called genes. . It is the main material basis for storing, transmitting genetic information and replicating cells. The storage and transmission of genetic information from one cell to the next and from an individual to its offspring involves a chemical mechanism. Watson and Crick created structural models of DNA to explain this mechanism. Genetics hide the secrets of life and its history and are born during the evolution of biochemical systems.
Genetic properties
Gene has three characteristics: ① stability. The molecular structure of genes is stable and not easily changed. The stability of genes comes from the precise self-replication of genes, which are distributed to daughter cells with cell division, or passed on to offspring through sex cells, thus ensuring genetic stability. ② determine the development of traits. The specific genetic information carried by the gene is transcribed into messenger ribonucleic acid (mRNA), translated on the ribosome into a polypeptide chain, and the polypeptide chain is folded into a specific protein. Some of them are structural proteins, and more are enzymes. It is through the control of enzyme synthesis that genes control every biochemical process of an organism, thereby controlling the development of traits. ③ variability. Genes can be mutated due to the influence of mutagenic factors inside and outside the cell. Mutations result in alleles and polyalleles. Because of this variability in genes, the existence of genes can be recognized, and the diversity of organisms is increased, providing more opportunities for selection.
Genetic diagnosis and testing
By analyzing the human genome using microarrays, genetic genes that cause disease can be identified. Cancer, diabetes, etc. are all diseases caused by genetic defects. Medical and biological researchers will be able to identify, in seconds, mutated genes that ultimately lead to cancer and more. With a small drop of test fluid, doctors can predict how well a drug will work on a patient, diagnose adverse effects of a drug during treatment, and identify on the spot what bacterial, viral or other microbial infection a patient has. Using gene chips to analyze genetic genes will make the diagnosis rate of diabetes more than 50% after 10 years.
Genes come from parents and are almost unchanged throughout life. However, due to genetic defects, some people are naturally prone to certain diseases, which means that the existence of some genotypes in the human body will increase the risk of certain diseases. Genes are called disease susceptibility genes.
As long as you know the susceptibility genes for which diseases in the human body, you can infer which diseases people are prone to suffer from. However, how do we know which disease susceptibility genes we have? This requires genetic testing.
How is genetic testing performed? The exfoliated cells are scraped from the oral mucosa of the test subject with a special sampling stick. Through advanced equipment, researchers can obtain the test subject's DNA samples from these exfoliated cells, and perform DNA sequencing and SNP mononucleation on these samples. The nucleotide polymorphism test will clearly know the difference between the gene sequence of the test subject and others. After comparing with the gene samples of many types of diseases that have been found, you can find the DNA of the test subject. Which disease susceptibility genes.
Genetic testing is not the same as a medical diagnosis of a medical disease. The results of genetic testing can tell you how high your risk of developing a disease is, but it does not mean that you already have a certain disease, or that you will definitely develop this disease in the future.
Through genetic testing, people can be provided with personalized health guidance services, personalized medication guidance services, and personalized physical examination guidance services. It is possible to carry out accurate prevention years or even decades before the occurrence of diseases, instead of blind health care; people can adjust their diet and nutrition, change their lifestyles, increase the frequency of physical examinations, and receive early diagnosis and treatment. Environmental factors that prevent disease occurrence.
Genetic testing can not only tell us in advance how high our risk is, but it may also clearly guide us to take the right medicine and avoid the harm that medicine can do to us. It will change the situation of indiscriminate drugs, ineffective drugs and harmful drugs and blind health care in traditional passive medicine.
