Here are the top 6 myths about DNA and some corrective observations.
More properly, DNA (deoxyribonucleic acid) is a molecule of nucleic acid.
DNA is only found in people
No, it’s found throughout all living things in nature, though of course it differs in terms of its coding from one life form to another.
By way of instance, if you have any pet critters they’ll also have DNA.
Life Can’t exist without DNA
This is a really tricky one since you can argue for quite a lengthy time period about whether matters such as viruses are alive or not.
Should you think that viruses constitute life, then the statement is not entirely accurate. Some viruses do contain DNA while some don’t and use rather RNA (Ribonucleic acid) as a method of communicating genetic information. HIV is 1 example of a virus that doesn’t contain DNA.
Theoreticians also have speculated as to whether more sophisticated life may develop without DNA and some are convinced that there’s not any reason why an alternate mechanism for passing on genetic information couldn’t have developed elsewhere. This is a choice discussion point amongst the scientific community debating whether extra-terrestrial life exists.
It’s Hard to extract DNA
No, it is not.
In actuality, the fundamental chemistry behind the procedures is now relatively straightforward and related experiments are often conducted in several schools as part of the science lessons.
It’s only useful, in an applied sense, in forensic work
On the contrary, knowing DNA and possibly using that understanding to create treatments, is among the fastest-growing and possibly most promising areas of medical research today. A whole assortment of treatments seem to be breaking from this field.
It’s also proving to be quite helpful in understanding the evolutionary history of various human and other animal populations around the world. This is sometimes known as DNA-archaeology or DNA-anthropology etc..
More commercially, organisations are currently encoding unique DNA markers into products to be able to make certain that they can’t be readily or profitably be faked and counterfeited. These are sometimes known as”brand integrity solutions.”
You can utilize DNA at birth to predict all the disorders someone will get as they get older
Unfortunately, you can’t.
While this is frequently depicted in science fiction books and movies, at the current time it’s only possible to analyse the DNA of a recently born child to search for a relatively few of certain identified issues that will signify he or she will develop a specific condition in the future.
In other situations, it’s now known that certain genetic combinations can indicate that the person concerned will have specific genetic predispositions towards a state later in life. That is far from the exact same thing as saying that medical science can now say with certainty that they will develop these conditions.
Numerous illnesses in life are linked to lifestyle choices or the misfortune of picking up something infectious. These might be entirely unrelated to your genes. So, as not all diseases and conditions are directly linked to genetics they can’t be predicted by analysis at birth.
