Suppose a geneticist mutates the gene for the poly(a) tail-binding protein (pabp) in an eukaryotic cell line. the resulting mutant protein cannot bind to poly(a) tails. what is the effect of the pabp mutation in the cultured cells? a-transcription will not occur in the cultured cells, because pabp is an essential transcription factor. b-translation will not occur in the cultured cells, because mrnas will be degraded at a greater rate than normal. c-transcription will occur in the cultured cells, but the resulting transcript will be longer than normal. d-translation will occur in the cultured cells, but the resulting polypeptide will be longer than normal. e-replication will not occur in the cultured cells, because pabp determines the location of the origin of replication.
