Scientists Have Inserted a Gif of a Horse into Living Bacteria

Mind boggling DNA wonders!


As we know, basic Biology lessons in school and further, for people who have studied in the future, DNA has a wide spectrum usage in genomic studies as well as genetic dispositions in our entire human race. This technology news now run through our news feed every morning. Genes are what differentiates a human being from the rest of the crowd, genes are what we carry from our parents to future generations, and these molecular level proteins ultimately runs the living race in the world. From bacteria, to viruses and human beings- everything is governed by genes.

With inventions running in every genetic lab in the world, current genetic engineers and researches have managed to insert a GIF of a horse into live bacteria. Yes, shocking indeed.

Astonishing inventions!

A GIF of a moving horse has now been successfully incorporated into a bacterium, that too a live one! The genetic tool called CRISPR is often used in the genetic world for data storage purposes. It is a mind boggling wonder tool in the genetic tool which allows genetic professionals to explore the wide spectrum and possibilities of DNA and its uses in the near future. Medicine holds a lot of scope, thanks to this technology.
The technological news says that scientists in Harvard University have managed to incorporate CRISPR associated proteins called Cas1 and Cas2 as primers which will be programmed to work as a computer’s Ctrl-X tool. This enables scientists to manipulate with the DNA segments, interchange them and club them if needed.

Using the Cas1 and 2 sequences, the iconic horse GIF has been encoded and put together with high accuracy. What the CRISPR technology does is, it codes the pixel values of black and white horses and incorporates it into the genomic sequence of a live bacteria! Astonishing indeed!

The results showed spectacular multiplication of the bacteria and also hereditary patterns in the following generations.

The point of this invention is the purpose of data storage. DNA is a great device of data storage, and using this technology as per the technology news, we can access vital information about genomic studies with ease. The amount of data that a single gram of DNA can hold could possibly be information of the entire human race, all crammed into one room, which is truly insane.

DNA technologies have progressed highly over the years and will continue to do so. But with this GIF incorporation, a news meaning and growth of genomic studies and researches have been established. The wide spectrum and diversity of this technology will be a boon to the medicinal world and curing of lethal genetic diseases. Various novel syndromes and anomalies can be detected at such early stages, which would previously be unimaginable. With the hope of further growth of the technological wonders of DNA this new invention is cherished and will possibly change the way medicine is perceived.

Genetics is finally a Modern Science



Everything is genetically determined once and for all and our genes determine our health, that's what we told the old doctrine preformationism which since the seventeenth century, states that all living is already preformed in the germ and in the embryo, and that it is not subject to transformation. Since the speech has hardly changed, unfortunately ... For the truth is otherwise. This is a new science that tells us: epigenetic. It states that genes are expressed or not according to our habits, our lifestyle, our relationship with nature, our food, but also, unfortunately, many pollutants we are exposed. In summary, the epigenetic theory demonstrates the influence of environment on the functioning of genes.

One lived in town, had poor hygiene, poor health and several cancers. The other, living in the countryside, do not develop the genetic disease, however, could be programmed by the same genes. The epigenetic states that can influence gene expression without altering the genome of the individual. For example, some genes can be repressed and no longer will encode disease while others will put in operation and protect us. The former can cause cancer and prevent others. The action is not direct but depends on environmental factors that influence the proteins on which DNA is wound. Thus one can, in animals, change the color of the skin by acting on purely functional factors. This also means, unfortunately, that some chemicals that we did not know carcinogens may become inducing stimulation of genes expected to be inhibited. It is now recognized as bisphenol A, a plastic hardener now known to all, would imply a deregulation of the gene encoding adiponectin, the hormone of satiety that protects us from diabetes.

For epigenetic, nutrition plays a key protective role. One thinks, for example, that vitamins like B9, B12, provided they are natural, or certain foods like broccoli and avocado, make reversible expression of disease genes. Vitamin C blocks the expression of hereditary diseases such as Charcot-Marie-Tooth. So much the worse for those who thought it sufficient to change the picture of our genetic identity card to change our future.
