What is unhealthy DNA?
junk DNA is DNA that seems to have no recognizable function. However, the term "unhealthy" is a bit misleading because research on unhealthy DNA has suggested that it can actually play an important role in the evolutionary history and lives of many organisms. Rather than a junk, this DNA may actually be stored for a critical reason and scientists have begun to explore unhealthy DNA to learn more about it. Whatever you call it, the percentage of unhealthy DNA in the genome is often relatively high. For example, in humans, 95% of the genome is composed of non -coding DNA. It seems that unsolicited DNA explains a large part of the differences in the size of the genome between different organisms, because some plants and animals have a large amount of spam, while others have less. For example, the huge sections of the non -coding DNA is what is called "ultraconsevated", which means they remained the same for millions of years. Scientists know that these sections are ultra -concreted because they are identical in many organisms, sometimes in the case of creatures that aren remotely connected. When you take the claim as "An animal genome and humans are 98% identical," it is because of ultra -conserved DNA.
Looking at the differences in unhealthy DNA among organisms, scientists could learn more about when these organisms were different from ordinary ancestors. It seems that the fact that non -coding DNA has been maintained for millions of years suggests that it has a function, perhaps in the role of regulation of gene, gene repair or gene evolution. It also seems that non -coding DNA acts as a buffer in a genetic code that can play a role in DNA replication.
existed evidence that some of the sections in unhealthy DNA were once active genes, which led to scientists to indicate these sections as "pseudogenes". At some point in evolutionary history, these genes were considered unimportant or replaced by other genes, but remained quietly in the background. Non -coding DNA can also play a role in the heritage of illness and otherH properties, which means it may not be unhealthy in the end.
