Surprisingly large segments of DNA found to differ from person to person.
Same but different
- 3,080 million 'letters' of DNA in the human genome
- 22,205 genes, by one recent estimate
- 10 million single-letter changes (SNPs) — that's only 0.3% of the genome
- 1,447 copy-number variants, covering a surprisingly large 12% of the genome
- About 99.5% similarity between two random people's DNA

0.5% left to differenciate each individual. It's an interesting thing to think about. Sometimes just one SNP, a change in a single nucleotide of our DNA, in our genome can damage us and don't let us be alive. Sometimes 0.5% differences between two people can make them fit like two puzzle pieces and stay together for the rest of their lifes.
I liked a sentence of the movie I saw yesterday Ficció (2006) (Ficció in imdb ... click me!):
"... from time to time, it's nice to fall in love ..."
