Groundbreaking Discovery

A team of 99 researchers led the groundbreaking discovery by identifying about 115 new genes that code for proteins.

The Telomere-to-Telomere (T2T) Consortium, an international collaboration that comprises around 30 institutions, has released data that gives new insights into the workings of the DNA and how it influences risks of disease and how cells keep it in neatly organised. Experts say that the new details will open our eyes to critical information stored within DNA that had remained elusive forever.

Why Did It Take So Long To Decipher The Human Genome?

Scientists identified 3.055 billion base pairs (“letters”) of our DNA code as they made the data public. However, the wait has been over two decades since the first draft was released in 2001. Scientists have known for decades that genes were spread across 23 pairs of chromosomes.

As long stretches of the genome remained unknown , scientists struggled to understand where millions of bases fit. While they released the first draft in 2001, the reference genome draft was released in 2013 where they had read these fragments more accurately.

Scientists decipher the complete human genome & found new genes.

In February 2001, when researchers released the first set of the human genome sequence, it was a seismic event in the history of life sciences. However, it was not truly complete and 15 per cent of the genome was still to be deciphered. The most complicated chunk of DNA called for further research and technological advancement.

What Is A Human Genome?

A genome is an organism's complete set of DNA, the chemical compound that contains the instructions needed to develop and direct the activities of nearly all living organisms. They are made of two twisting, paired strands often referred to as a double helix. Each DNA strand is made of four chemical units, called nucleotide bases, which comprise the genetic "alphabet."

Virtually every single cell in the body contains a complete copy of the approximately 3 billion DNA base pairs, or letters, that make up the human genome. DNA contains the information needed to build the entire human body.

The Human Genome Project

The project has revealed that there are probably about 20,500 human genes and the information about their structure, organization and function can be "thought of as the basic set of inheritable 'instructions' for the development and function of a human being."

A startling finding of this first draft was that the number of human genes appeared to be significantly fewer than previous estimates, which ranged from 50,000 genes to as many as 1,40,000.

What is the Human Genome Project?

The Human Genome Project that first realised its goal in 1988 aimed to decipher the human genome in three major ways:

  • Determining the order, or "sequence", of all the bases in our genome's DNA
  • Making maps that show the locations of genes for major sections of all our chromosomes
  • Producing what is called linkage maps, through which we inherit trait

Humans share 98.8% of their DNA with chimpanzees. Because gene expression can be turned up or down-similar to the volume on your TV-the same gene can be turned to "high" in a human and "low" in a chimp. The human brain is larger and smarter than that of chimps and gorillas because, although we all have the same genes in the same brain region, these genes are expressed in different "volumes" or amounts. It is these differences that affect brain development and function.

Human Evolution

Evolution is a gradual change in the DNA of a species over many centuries, occurring by natural selection when traits created by genetic mutations promote survival or reproduction in an organism.

By looking at global DNA studies, it is evident that human evolution hasn’t stopped, but is happening at a faster rate than before.

The human stomach can dissolve razor blades

On the rare occasion that you swallow a razor blade, don’t fret. The human body is more capable than you think. Acids are ranked on a scale from 0 to 14—the lower the pH level, the stronger the acid. Human stomach acid is typically 1.0 to 2.0, meaning that it has an impeccably strong pH. In a study, scientists found that the “thickened back of a single-edged blade” dissolved after two hours of immersion in stomach acid.
