alpha-amanitin is an extremely deadly toxin produced by death cap mushrooms. It specifically blocks the activity of RNA polymerase II, but not other RNA polymerases. Based on what we've learned in class so far, what's the most likely molecular mechanism leading to fatality when a human eats a death cap mushroom? Group of answer choices Failure to transcribe rRNA Failure of sigma factor to bind to promoter Failure to replicate DNA Failure to transcribe pre-mRNA Failure to transcribe tRNA Failure to translate polypeptides
Bacterial Genomics
The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.
Transformation Experiment in Bacteria
In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.
Plasmids and Vectors
The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.
Alpha amamitin is a toxin produced from Amanita phalloides, a death cap mushroom. This species of mushroom contains a white stem, greenish cap, and white gills. These species are mostly found in pine, oak, and other woodlands of Europe and North America. These species release alpha-amanitin that inhibits the activity of RNA polymerase Ii, thus inhibiting transcription.
