Genes and proteins

This material fits in nicely with my current coursework...
  • Since there is no such thing as "the" human genome, everyone varies slightly in their DNA's nucleotide (A, G, T, C) sequence, and therefore in their amino acid sequence. Since one different nucleotide can mean a different amino acid, and from there a potentially different protein shape, this also affects dosages of various drugs. Here is a case in point.
  • Alzheimer's disease has been elsewhere connected with prions (misfolded proteins); here is suggested a prenatal link. The investigation continues.
