Deoxyribonucleic acid (DNA) contains the genetic instructions for all known living things. And scientists at the US space agency NASA have created an "alien" form of DNA. This DNA could lead to breakthroughs in understanding what alien life could resemble.
The NASA discovery suggests that there might be unimagined forms of DNA-based life as we know it on Earth
And alien life on other worlds might be built using (19659004) The new molecular system will allow scientists searching for alien life to recalibrate what exactly they are actually looking for and where it could exist. and complex double helix-shaped molecule stored and then transmitting the genetic information that makes us who we are.

Lori Glaze, acting director of NASA's Planetary Science Division, said: "Life detection is an increasingly important goal of NASA's planetary science missions, and this new work will "
The new research saw scientists create a new kind of molecule system that functions like DNA, but it has an important difference. 19659004] NASA scientists have created one containing eight
It has all of the four that are found in life on Earth: adenine, cytosine, guanine, and thymine

"
The NASA study seems to have demonstrated how life could structure itself in different
This means unimagined alien life forms could be thriving in environments never before considered by those searching for it.
Mary Voytek, senior scientist for Astrobiology at NASA Headquarters said : "Incorporating a broader understanding of what is possible in our instrument design and mission concepts will result in a more inclusive and therefore more efficient search for life beyond Earth.
