Why is it important that the cell’s DNA is duplicated before cell division?

Give an example of a trait that is controlled by more than one gene.

Construct at least two possible hypotheses for the student’s experiment.

Ras is a g-protein that is activated when a growth factor attaches to egfr. its activation results in the replacement of a gdp molecule with a gtp molecule, thus allowing a signal transduction pathway to be activated. considering the signal pathway illustrated on this page, what is one potential outcome of a mutation in the ras gene that leads to ras protein hyperactivity. be specific.
