As expected, they found that the normal and extra-long genetic instructions were both translated
into huntingtin proteins when they met up with a ribosome (the chef from our analogy above).
an organism that has had one of its genes altered, for example by adding a long CAG repeat
into the huntingtin gene.

huntingtin, they thought, the peptides accumulated
into the abnormal globs seen in the neurons of Huntington's victims.
By placing aSyn and the
huntingtin protein
into the library separately and then monitoring each cell's reaction, they were able to deduce which genes are important for the cells to survive the toxic insult from aSyn, and which ones are needed to help the cells survive the
huntingtin protein.

huntingtin protein from being broken
into small enough fragments to enter the cell's nucleus and mess up the switching on and off of important genes.

into clumps (
huntingtin does this too).
