The genetic material must be capable of storing large amounts of information, including instructions for the traits + functions of an organism: the genetic material must faithfully (and accurately) replicate: At each cell division, the genetic instructions must be accurately transmitted to descendant cells. Also, when organisms reproduce and pass genes to progeny, the genetic instructions must be copied exactly: the genetic material must encode the phenotype and have the capacity to vary: The genetic material must have the capacity to code for traits; there must be a mechanism for genetic instructions in the dna to be copied into rnas and proteins.
