Which statements are true?
i.In thalassemia,globin proteins are produced,but contain a point mutation.
ii.In sickle-cell anaemia,globin proteins are produced,but contain a point mutation.
iii.Sickle-cell anaemia is caused by a mutation in the β-globin gene.
iv.Sickle cell anaemia is caused by a mutation in the α-globin gene.

Question

Quizplus · Accepted Answer

Both statements ii and iii are true. In sickle-cell anaemia, the β-globin gene is mutated, leading to the production of abnormal haemoglobin proteins, which cause red blood cells to take on a sickle shape. Thalassemia, on the other hand, is caused by mutations in the α- or β-globin genes, resulting in a decreased production of normal haemoglobin proteins. Therefore, statement iv is false.
