WebIn Brief: First, students read about protein synthesis, gene mutations, and chromosomal mutations. Then, students practice transcribing and translating mutated genes, identifying the type of mutation that occurred. Then, students read about protein structure, and put it all together using normal/sickle hemoglobin as an example. WebPeople with all types of SCD inherit the gene for hemoglobin S from 1 parent and a gene for another type of hemoglobin from 1 parent. Hemoglobin S (also called sickle hemoglobin) is the most common type of abnormal hemoglobin. It has a mutation that causes it to form rigid strands that make red blood cells stiff and sickle-shaped. 1 how to mod dead rising 2 pc
