NASA admits DNA came from outta space creating being on Earth. But what is a DNA or DNS in the first place?
The deoxyribonucleic acid (Des | oxy | ribo | nucleons | in | acid; short DNA, DNA english) (lat.-fr.-gr. art word) is in all living organisms and DNA viruses occurring biomolecule and the carrier of genetic information. It contains the genes encoding the information for the production of ribonucleic acids (RNA, the Germans also RNA) contain. An important group of RNAs, mRNAs containing the information again for the construction of proteins, which are necessary for the development of a biological organism and the metabolism in the cell. Within the protein-coding genes determines the sequence of bases, the sequence of amino acids of the protein: In the genetic code three bases stand for a particular amino acid.
In the normal state, DNA is organized into a double helix. Chemically, it is nucleic acids, long chain molecules (polymer) from the four different building blocks, the nucleotides are built. Each nucleotide consists of a phosphate group, the deoxyribose sugar and one of four organic bases: adenine, thymine, guanine and cytosine, often abbreviated as A, T, G and C.
In the cells of eukaryotes, which include plants, animals and fungi, the majority of the DNA in the nucleus is organized as chromosomes, a small portion is located in the mitochondria ("power plants" of cells). Plants and algae also have DNA in their chloroplasts, the photosynthetic organelles. In bacteria and archaea, the prokaryotes, which have no nucleus, the DNA is located in the cytoplasm. Some viruses, called RNA viruses have RNA but no DNA to store genetic information.
How did it come to earth? Maybe by an asteroid? Watch this video to find out:
