Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Mitotic anaphase is the most suitable stage to study the morphology of chromosomes. Reason (R): By metaphase, condensation of chromosomes is completed and they are made up of two sister chromatids held together by a centromere. In the light of the above statements, choose the most appropriate answe

Step-by-step solution

Assertion is false because metaphase, not anaphase, is the most suitable stage to study the morphology of chromosomes. This is because chromosome condensation is fully completed by this stage. Reason is true because during metaphase, the fully condensed chromosomes can be observed clearly under the microscope, and each metaphase chromosome is made up of two sister chromatids held together by a centromere. Therefore, Assertion is false but Reason is true. Answer: Assertion is false but Reason is true.
