Genes play a role everything we are, from our looks and skills to our brains and personality. Deciphering a gene means to understand that gene's role in our development. For instance people who suffer from sickle-cell anemia have differently shaped blood cells. When scientists isolated the genes responsible for constructing the specific blood cells affected by this type of anemia they claimed to have deciphered the genes responsible for sickle-cell anemia. Now everyone can be tested to see if they carry these defective genes and amniotic fluid can be drawn and tested to see whether an embryo has inherited the disorder from his parents or not.
