Question
A chromosome with a J-shaped anaphase configuration is most likely: a. telocentric b. acro-telocentric c. acrocentric d. submetacentric
Correct Answer
Option D is the correct answer.
Detailed Explanation
The shape of a chromosome during anaphase depends on the position of the centromere. A submetacentric chromosome has a centromere slightly off-center, giving it a characteristic J-shape as it is pulled. Acrocentric has a very short p arm, often appearing rod-like. Metacentric (centromere in middle) appears V-shaped.
Hint
The centromere is not in the middle, but also not at the very end.
