Term
Information
Definition
The genetic material must contain the information necessary to construct an entire organism.
Term
Transmission
Definition
The genetic material must be passed from parent to offspring. It also must be passed from cell to cell during the process of cell division.
Term
Replication
Definition
For transmission to occur, the genetic material must be accurately copied
Term
Variation
Definition
Differences in the genetic material must account for the known variation within each species and among different species.
