Taking coffee as an example, although drinking coffee can refresh the mind, the caffeine in it will increase the heart rate and blood pressure. Long-term consumption of excessive caffeine is more likely to cause irritability, mental tension and headache. Slow down cellular aging. So, does drinking coffee do more good than harm, or more harm than good? genome_1_3 Variations in the noncoding regions of DNA can affect the production of enzymes that destroy the caffeine molecule, making some people more likely to enjoy the benefits of coffee.
The answer to this question company banner design lies in the non-coding regions of the human gene map, which account for 98% of the map, and are regarded as "garbage" because they cannot directly produce proteins. This "junk" DNA can physically facilitate or prevent the enzymes that transcribe DNA into RNA from accessing genes in the coding regions, the study suggests. In the case of coffee, it controls the production of an enzyme that destroys the caffeine molecule. The more this enzyme is produced, the less long-term caffeine will have on the body, and the better the body will enjoy the antioxidant benefits. benefits. This situation has also appeared when studying the effects of long-term smoking on the human body.
The metabolism of nicotine is also affected by non-coding DNA. These results have important implications for medical planning in the future society. genome_1_2 It is also a long-term smoking, some people will suffer from all kinds of diseases, and some people will live a long life. The secret is written in 98% of the non-coding areas. Stunning detail reproduction - reconstituted suspect's face from a drop of blood From affecting the transcription of genes in the coding regions to how many enzymes are produced, the relationship is relatively straightforward, but the effects of DNA in non-coding regions on the human body go far beyond that. In TV and movies, there are often scenes where police or forensic officers collect evidence at the scene of a crime, many of which are human tissues, such as blood, dander, and hair. This is to obtain the owner's DNA for identification purposes.
