G protein can refer to two distinct families of proteins.

Explanation:

heterotrimric G proteins are large in shape, G proteins are activated by G protein coupled receptors and are made up of alpha (a) beta(b) and gamma(y) subunits.

during the process of dna replication, brdu can replace thymidine and incorporate into the newly synthesized dna, cell proliferation thus can be reflected in the extent of brdu incorporation.
