Which of the following biopolymers would you NOT expect to find in red blood cells?

You work as a genetic counselor and are presented with prospective parents worried about their children inheriting the recessive monogenic genetic disease that one of them has. The other parent, however, does not have any disease mutations in either copy of that gene. What is the probability that any one of their children will have the disease? For this calculation, assume no new (de novo) mutations occur.
