Which of the following statements regarding the classification of chromosomes based on the position of the centromere is incorrect?
Options
- AThe metacentric chromosome has a middle centromere forming two equal arms.
- BThe sub-metacentric chromosome has its centromere slightly away from the middle, resulting in one shorter and
- CThe telocentric chromosome has a terminal centromere.
- DThe acrocentric chromosome has a terminal centromere, forming one extremely short and one very long arm.
Correct answer
D. The acrocentric chromosome has a terminal centromere, forming one extremely short and one very long arm.
Step-by-step solution
Based on the position of the centromere, chromosomes are classified into four types. The metacentric chromosome has a middle centromere forming two equal arms. The sub-metacentric chromosome has its centromere slightly away from the middle, resulting in one shorter and one longer arm. The telocentric chromosome has a terminal centromere. The acrocentric chromosome has its centromere situated close to its end (not terminal), forming one extremely short and one very long arm. Therefore, the statement describing the a
