DNA - the distinctive characteristics or qualities of someone or something, especially as regarded as unchangeable
Transcription - the first step of gene expression in which a particular segment of DNA is copied into RNA
Translation - messenger RNA is decoded by a ribosome outside the nucleus, to produce a specific amino acid chain, or polypeptide. Which later folds into an active protein and performs, it's function in one cell.
Everyone in the world has DNA.
The end result of transcription is, An RNA molecule that carries the genetic information of DNA from the nucleus to the ribosomes in the cytoplasm, where the information is translated to a protein. RNA polymerase slices gene out of DNA molecule.
The molecule that results from translation is protein or more precisely, translation produces short sequences of amino acids called peptides that get stitched together and become proteins. During translation, little protein factories called ribosomes read the messenger RNA sequences. If mistakes happen during either of these processes it alters the DNA and changes what they are suppose to look like.
