VII. DNA/ GENES/ AND GENETICS • Describe the relationship
... Why can’t one cell in a multi-cellular organism function independently of that organism? Even though all cells in an organism contain the same genes, they can vary greatly in structure and function. How is this possible? What mechanism do cells use to turn genes on and off? Give examples of emerging ...
