Which linkages would you expect to find at a branch point in glycogen or amylopectin?

α-1,6-glycosidic linkage.

Explanation:

The carbohydrates are the polymers made of the sugars and bonded together through the glycosisdic bonds. The monosaccharides are the simplest unit of the carbohydrates.

The glycogen and amylopectin share similar structural features. Both have α-1,4-glycosidic linkage in their linear structure. The branching has been introduced in the glycogen and amylopectin structure through the α-1,6-glycosidic linkage.

Thus, the answer is α-1,6-glycosidic linkage.

the cell cycle is the final answer! : )

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
