Our body contains one hundred trillion cells, inside most cells is a nucleus that contains a complete set of the body’s blueprints. Those blueprints are twisted into forty-six packets called chromosomes. Unravel a chromosome, and you get the long, thread-like molecule called DNA. Within the DNA are the blueprints, called genes, for which make proteins. The DNA molecule has a twisted, laddershaped structure (the famous double helix). The genetic code can be read in the rungs of the ladder. T ...
