The mysterious part of DNA secret of human evolution: An important scientific effort 20 years ago let out that the human genome accommodates 20,000 protein-coding genes, but these genes make up only two percent of human DNA. All at once, it was the idea that the rest of the DNA was not meaningful, but now it is envisioned how meaningful it is.

In April 2003, a 13-year scientific attempt to untangle the riddle of the 'Book of Being' in the human genome was announced completely. There was a high supposition that between the ``Human Genome Project'', which cost three billion dollars, restoration for many complaints would be found and new confidentiality about human life would be revealed.

But at a press conference indicating the dawn of an up-to-date era of biological understanding, this informative instructions on human life came as an unforeseen stunner.

At the time, it was widely accepted that the majority of the human genome would contain the instructions for making proteins, the basic building materials in every structure that perform surprising roles inside and outside cells. There are further than 200 kinds of cells in the human body, and it was not amazing to visualize that each cell would need another kind of genetics.

Yet it was discovered that just about 20,000 of the three billion characters in the human genome—less than 2%—are set aside for proteins. Geneticists were startled to learn that humans have as numerous protein genes as many alternative structures on Earth.

This disclosure put the world of science in a new enigma and the question arose in front of them that our recognition of Shahid was wrong.

Sameer Haya is the chief executive of a therapeutics enterprise that is trying to understand human genetics to discover cures for heart disease, cancer, and other diseases.

"I recall the short time when many people got going to wonder if our ideas about biology might be wrong," he says.

The remaining 98% of human DNA has been named 'dark matter' or 'dark genome'. It was a mysterious mass of letters whose meaning we neither knew nor the purpose of.

Some geneticists initially suggested that the dark genome probably had no purpose and was the garbage collected by human evolution, leftover bits of genetics that lost their purpose over time.

However, other experts believed that the genome was essential to understanding humanity.

Carrie Stephenson is the chief executive of Decode Genetics. "There is no place for garbage in development," she says. There should be an argument for the size of the genome to endure the same.

After two decades, some information about this dark genome is emerging. Its main purpose is to keep the decoding process of genes that make proteins going and it controls the behavior of human genes in environmental or external stressors that the body faces, including factors such as diet, exercise, sleep, etc. Called 'Epigenetics'.

Sameer speaks he thinks proteins are the hardware of life, while the dark genome is the software, and the more we learn about this cryptic genome, the more we can learn about human complications.

"Man has always accommodated to the environment, and when we think about why we are distinct from a fly, the answer recline in the dark genome," he speaks.

Evolutionary past

When scientists began reading the Book of Life, DNA, around the year 2000, one strain was that the parts of the human genome that did not code for proteins hold many forms of similar DNA called 'transposons'. ' is called.
They were so generous that half the genomes of all mammals contain them.
Jeff Boeck runs the Dark Matter Project at New York University. "Early human genomes were made challenging by these similar DNAs because it's accessible to dissect DNA if it's distinctive," he speaks.
Geneticists to begin with ignored transposons and concentrated on the genome's tiny protein-coding 'exome'. But proceed in technology over the past decade have made it realistic to better examine the dark genome.
In one experiment, an analyst removed a specific transposon in the DNA of mice from an animal that follow in further than half of its offspring dying before birth. This indicates that some transposons may be essential for our existence.
The company of transposons in the genome may be explained by the fact that they are completely ancient, dating back to the before-time forms of life on Earth, says Jeff Boeck.
Other scientists say they are caused by viruses that have attacked DNA throughout human history but over time integrated into the body for further occasions.
Jeff Boeck considers the Dark Genome to be the most important living record of changes in human DNA that occurred long ago.

Transposons are interesting because they can travel between genomes, which gives them their name because they can drastically alter genetics.

Due to their similar movements, it is possible that the monkey family died out and the man also started walking upright.
Jeff says it was a change that had a profound effect on evolution.
But while the dark genome may reveal the secrets of human evolution, it may also reveal how a disease develops.
Sameer says research shows that most of the genetics linked to long-term diseases, such as diabetes and heart disease, are not in the protein-coding parts of DNA, but in the dark genome.
