PLEASE HELP!! Amino acids form peptide bonds through dehydration. Explain the role of water in this process by describing the chemical reaction. (Note: You do not need to draw molecular structures in your answer.)

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.
