AIIMS 2018 Botany Genetic Disorders MCQ Question

Option C is correct because it identifies B as valine, which is significant in the context of certain genetic disorders, such as sickle cell anemia, where a single nucleotide mutation leads to the substitution of glutamic acid (Glu) with valine (Val) in the hemoglobin protein. Option A is incorrect as it does not pertain to the inheritance pattern of the trait in question; autosomal dominant traits would not be relevant without specific context. Option B is incorrect since it misidentifies B as glutamic acid, which is not the case in this scenario. Option D is also incorrect because the conditions discussed are genetic and not caused by bacteria, emphasizing the importance of understanding the molecular basis of genetic mutations.
