If a toxin blocked an organisms ability to undergo transcription, what else would the cell not be able to do ?

The cell would be unable to create proteins

Explanation:

Transcription is the process by the DNA is read by RNA polymerase to create mRNA. The mRNA is then used by ribosomes to create proteins by recruiting respective amino acids that correspond to the codon sequence on the mRNA (in a process called translation).  

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
