Question

Hemoglobin is the protein in red blood cells that binds oxygen. If a mutation occurs in the DNA that codes for hemoglobin, thestructure of hemoglobin can change. The change in structure of hemoglobin can then change the shape of red blood cells, andsome mutations can cause red blood cells to become sickle-shaped.sickled red blood cellnormal red blood cellSickled red blood cells carry less oxygen than normal red blood cells. What does this demonstrate about mutations in the DNA thatcodes for hemoglobin?A. These mutations decrease the amount of oxygen available to bind with hemoglobin.B. These mutations can change the structure and function of hemoglobin.C. These mutations can change the structure of oxygen so that it does not bind to hemoglobin.D. These mutations are unable to affect the structure and function of hemoglobin.ResetSubmit

Answer 1

Red blood cells are sickle shaped because of their DNA

Answer 2

The fact of producing sickle-shaped red blood cells due an DNA mutation, as the exersice states, cause oxygen to not bind efficiently to these cells of our body, as states the B answer option with "these mutation can change the structure and function of hemoglobin".
