Chart the path of molecules of a secreted protein beginning at the DNA for a eukaryote What will be an ideal response?
The DNA message on the gene would be converted to RNA in the nucleus. The RNA would leave the
nucleus and travel to the rough endoplasmic reticulum. At this point it would bind to a ribosome for
translation to protein. The protein would leave the rough ER in a vesicle, travel to the Golgi apparatus
for sorting, and then put in a new vesicle. This vesicle would travel to the cell membrane to be
secreted.

Answer the following statement true (T) or false (F)
Type 1 fucosidosis is a rare human disease. Patients cannot hydrolyze the disaccharide fucose, and as a result have severe neurological decline and die by age 6. The disease is due to a defect in the gene that encodes the lysosomal enzyme that breaks down fucose (?-1-fucosidase), and is inherited in an autosomal recessive manner. Which of the following statements is accurate about Type 1 fucosidosis?
A. Ff individuals will have the disease, because anyone with the mutant allele will have the disease B. Ff and ff individuals will have the disease C. Two carriers for Type I fucosidosis have no chance of having a normal child D. Ff individuals make enough ?-1-fucosidase to break down fucose and do not exhibit the condition E. Both Ff individuals will have the disease, because anyone with the mutant allele will have the disease AND two carriers for Type I fucosidosis have no chance of having a normal child
