The scientists analyzed the meteorite that formed billions of years ago before falling to Earth. Carbon rich fractions were found to contain chemicals similar to the key components of "DNA", "the building block of life. "
The test results indicate the presence of these chemicals can not be explained by contamination with the Earth. It reinforces the DNA came from outer space. These findings come from U.S. scientists, formerly a NASA scientist.
Scientists have been analyzing the chemicals forming 12 meteorites and these findings have 'implications are very far away'. Study's lead author, DR. MICHAEL CALLAHAN, of NASA's Goddard Space Flight Center in Maryland said, "When meteorites and comets hit the Earth early, the object appears to send 'spice' which is very important."
The results of previous studies found that meteorites are two of the three basic ingredients of life forming. Among such written Dailymail, amino acids required for the cell is able to create a protective membrane. These chemicals are the third -forming DNA.
The results of this study were published in the journal Proceedings of the National Academy of Sciences.
