Globin chain switching replaces gamma chains with _____ chains in adult hemoglobin.
A) epsilon
B) zeta
C) beta
D) alpha
E) phi beta kappa

Question

Quizplus · Accepted Answer

Globin chain switching involves the replacement of gamma chains with beta chains in adult hemoglobin, resulting in the formation of HbA (alpha2beta2) as the predominant hemoglobin molecule in adult circulation. Epsilon and zeta chains are not typically present in adult hemoglobin, and alpha chains are always present in both fetal and adult hemoglobin. Phi beta kappa is not a type of globin chain.
