Answer:
The answers are :
Explanation:
A. Hidrolyisis- deficient RAS mutant :1. Continual activation of the MAP kinase pathway even in the abscence of signaling molecule, 5.Change in the expression of genes in the absence of the appropriate signaling molecule
C. High GDP affinity RAS mutant: 2.Failure to activate MAP kinase pathway following ligand binding to receptor kinase, 6. Target genes are not expressed even in the presence of signaling molecule
B. Neither: 3. Failure of receptor kinase to dimerize in the presence of ligand, 10. A continuously activated receptor in the absence of ligand
