A single amino acid change in Ras eliminates its ability to hydrolyze GTP, even in the presence of a GTPase-activating protein (

GAP). Roughly 30% of human cancers have this change in Ras. You have just identified a small molecule that prevents the dimerization of a receptor tyrosine kinase that signals via Ras. Would you expect this molecule to be effective in the treatment of cancers that express wild type or mutant form of Ras

Answer:

Yes, this molecule will be useful in the treatment of cancer.

Explanation:

Generally ligand binds to RTK——————— > RTK dimer formation————— > autophosphorylation occurs in RTK—————— > RTK activation—————— > This RTK activates RAS—————- > which activates many cellular processes————- > cancer.

Already, it nanoparticle stops RTK dimerization. As a result, RTK will not be triggered but the above-described sequence of activities would not be able to happen (from bold above); therefore, cancer can be precluded.

What is the definition of plate tectonics?
zhuklara [117]

The definition from what I know because I remember it from biology I think is "a theory explaining the structure of the earth's crust and some other associated phenomena as resulting from the interaction of a rigid lithospheric plates that move slowly over the underlying mantle." I'll put the quotations for you to copy what I said so it doesn't sound like you got it off me and I hopefully spelt lithospheric right
