D. The death cap mushrooms produce a toxin called Amanita phalloides, this toxin can be fatal to humans. Amatoxins are comprised of a ring of amino acids that hinder the production of specific proteins within liver and kidney cells. Without these proteins, cells can no longer to function adequately. (Fisher and Bennette,2012) Amanita phalloides have the ability to inhibit an enzyme called RNA polymerase II, this enzyme allows mRNA to take place. mRNA is the processes of making a copy of DNA. In the eukaryotic cells, the amanitin toxin directly interacts with an enzyme called RNA polymerase II; thus, decreasing transcription of mRNA (Nardo, 2012). Thus causing cellular death.
