He concluded that these three genes must act in the same pathway.
The genes act by switching on and off to produce certain proteins and other chemicals.
What is the dynamic context in which the genes are acting?
Your genes act like a virus, spreading throughout the person's body.
These genes, in turn, act as direct controllers of flower development.
Clones are genetic copies of the original, though they might not be the same in all details because the environment influences how genes act.
He and colleagues then established that another gene, named ced-9, acted as a master switch.
They then discovered that the gene normally acts as a sort of molecular sentinel.
If the two species are genetically different, there is little possibility that the genes from both will act harmoniously in the hybrid.
We know a good deal now about the way in which the genes act.
