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).  

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
