Here are the top 6 misconceptions about DNA and some corrective observations.


More correctly, DNA (deoxyribonucleic acid) is a molecule of nucleic acid.

DNA is only found in humans

No, it is 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 animals they’ll also have DNA.

  1. Life cannot exist without DNA

This is a very tricky one because you can argue for quite a lengthy period of time about whether matters such as viruses are alive or not.

If you do think that viruses constitute life, then the statement isn’t entirely accurate. Some viruses do contain DNA while others don’t and use rather RNA (Ribonucleic acid) as a method of communicating genetic information. HIV is one example of a virus that doesn’t contain DNA.

Theoreticians also have speculated as to whether more advanced life may develop without DNA and some are convinced that there is no reason why an alternate mechanism for passing on genetic information could not have developed elsewhere. This is a prime discussion point amongst the scientific community debating whether extra-terrestrial life exists.

It’s difficult to extract DNA

No, it isn’t.

In fact, the basic chemistry behind the processes is now relatively simple 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

To the contrary, knowing DNA and potentially using that understanding to create treatments, is among the fastest-growing and potentially most promising areas of medical research today. A whole assortment of treatments seem to be breaking from this field.

It is 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 in order to ensure that they can’t be easily or profitably be faked and counterfeited. These are sometimes referred to as”brand integrity solutions.”

  1. You can utilize DNA at birth to forecast all the disorders someone will get as they get older

Unfortunately, you can’t.

Although this is often depicted in science fiction novels and films, at the present time it is only possible to analyse the DNA of a recently born child to look for a relatively small number of certain identified problems that will signify he or she will develop a specific condition in the future.

In other situations, it’s now understood that certain genetic combinations can mean that the person concerned will have certain genetic predispositions towards a condition later in life. That is far from the same thing as stating that medical science can currently say with certainty that they will develop those conditions.

Numerous illnesses in life are linked to lifestyle choices or the misfortune of picking up something infectious. These may be entirely unrelated to your genes. So, as not all diseases and conditions are directly related to genetics they cannot be predicted by analysis at birth.
