It would stretch for 500 miles. What's going on now in the Human Genome Project is the transcribing of that message, from one end all the way to the other. So we have the message. Trouble is, we don't know what it all means. A library of protein recipes What scientists have looked for so far is the codes for proteins.
Proteins are important enough.
They're most of the fancy stuff we're made of, that makes our bodies work. They're big molecules made up of smaller protein pieces called amino acids, many of them, as many as tens of thousands. To them, it's a library of recipes for making proteins from amino acids. They think it's a library of recipes for making proteins because that's what they expected.
