In sickle cell anaemia the mutation is caused by single point i.e missense mutation.In beta cells the 6th base adenine is replaced with Uracil which means GAG(glutamic acid)codon is converted to GUG(valine).So option A is correct.

Direction: Read the following text and answer the following questions on the basis of the same :Sickle cell anaemia is a genetic disorder where the body produces an abnormal haemoglobin called haemoglobins. Red blood cells are normally flexible and round, but when the haemoglobin is defective, blood cells take on a “sickle” or crescent shape. Sickle cell anaemia is caused by mutations in a gene called HBB.It is an inherited blood disorder that occurs if both the maternal and paternal copies of the HBB gene are defective. In other words, if an individual receives just one copy of the defective HBB gene, either from mother or father, then the individual has no sickle cell anaemia but has what is called “sickle cell trait”. People with sickle cell trait usually do not have any symptoms or problems but they can pass the mutated gene onto their children. Three inheritance scenarios can lead to a child having sickle cell anaemia :— Both parents have sickle cell trait— One parent has sickle cell anaemia and the other has sickle cell trait— Both parents have sickle cell anaemiaIf both parents have sickle cell trait, then there is _______________of the child having sickle cell anaemia.
