2. Silk contains the repeating sequence
(Gly-Ser-Gly-Ala-Gly-Ala)n. This sequence is present in beta
strands that interact with each other. Considering just a single
strand within a sheet, the Ser and Ala side chains will be
(on both sides of the sheet in a single repeat) (in first repeat,
on one side; in the next repeat on the other side) (the answer
depends on whether the strands are parallel or antiparallel) (on
the same side of the sheet).
