Chapter 19, Problem 54FB
Summary Introduction
To review:
The given blank space in the statement“A ________________ is a purine-rich sequence close to AUG (the initiation codon) on a prokaryotic mRNA that binds to a complementary sequence on the 30S ribosome subunits, thereby promoting the formation of the correct preinitiation complex.”
Introduction:
The translation process of prokaryotes is the process in which protein formation takes place by decoding the base sequence of the messenger ribonucleic acid (mRNA). The first step of translationis the initiation step, which involves three initiation factors (IF), namely, IF1, IF2, and IF3. The ribosomal machinery carries out translation.

Help me understand how carbon disulfide leads to toxicity in the brain, using terms like distal axonopathy, neurofilaments, covalent cross-linking, adducts, etc.,...please intuitively explain what is happening and where and the effects of it. For example, I know that CS2 reacts with amide and sulfhydryl groups on proteins, but what proteins exactly and where are they located?
