Even though DNA repair enzymes correct most errors,approximately 1 in every one billion nucleotides still contains an error.The human genome,however,is 3 billion bases long.In an average adult,there are 50 trillion to 100 trillion cells,all of which contain these 3 billion bases,and these trillions of cells divide all the time.Given all this,why do you think people don't have cancer more often?
