The Kallisto Effect

Genetic code

The way in which instructions for building proteins, the basic structural molecules of living matter, are
`written´ in the genetic material DNA. This relationship between the sequence of bases (the subunits in a DNA molecule) and the sequence of  amino acids (the subunits of a protein molecule) is the basis of heredity. The code employs codons of three bases each; it is the same in almost all organisms, except for a few minor differences recently discovered in some protozoa.
Only 2% of DNA is made up of base sequences, called exons, that code for proteins. The remaining
DNA is known as `junk´ DNA or introns
