Question

The two embryonic globins are zeta (ζ) and epsilon (ε). What are zeta and epsilon globins a component of?

1) Hemoglobin Gower
2) Hemoglobin A
3) Hemoglobin F
4) Hemoglobin S

Answer 1

Zeta (ζ) and epsilon (ε) globins are components of Hemoglobin Gower, which is one of the forms of embryonic hemoglobin.

Step-by-step explanation:

Zeta (ζ) and epsilon (ε) globins are embryonic components of Hemoglobin Gower. Hemoglobin is a complex protein that carries oxygen in the blood and consists of globin proteins and heme groups. In adults, hemoglobin is typically comprised of two alpha (α) and two beta (β) chains, while embryonic and fetal forms have different compositions.

Hemoglobin Gower, one of the forms of embryonic hemoglobin, contains zeta and epsilon chains, distinguishing it from the common adult hemoglobin (Hemoglobin A), fetal hemoglobin (Hemoglobin F), and other variants such as Hemoglobin S and Hemoglobin A2.
