Question

Quizplus · Accepted Answer

Activation of receptor tyrosine kinases involves the dimerization of two receptor molecules and subsequent phosphorylation of their intracellular domains by each other. This leads to the activation of downstream signaling pathways. The other options listed are not characteristic of receptor tyrosine kinase activation.
