Question

After Ras is activated, what happens next?

A) Activation of transcription factors
B) Deactivation of downstream kinases
C) Inhibition of gene expression
D) Internalization of membrane receptors

Answer 1

After Ras is activated, the next step is the activation of transcription factors.

Step-by-step explanation:

After Ras is activated, the next step is the activation of transcription factors. Ras protein stimulates a phosphorylation cascade leading to the activation of MAP kinase. The MAP kinase then phosphorylates transcription factors and other nuclear proteins. These phosphorylated transcription factors can then bind to specific DNA sequences and regulate gene expression, leading to cell proliferation and differentiation.
