Three levels of condensation are required to package metaphase chromosomes.In order of complexity,lowest to highest,they are:
A) Supercoiling into nucleosomes, chromatin fiber condensation, scaffold formation
B) Chromatin fiber condensation, supercoiling into nucleosomes, scaffold formation
C) Scaffold formation, supercoiling into nucleosomes, chromatin fiber condensation
D) Supercoiling into nucleosomes, scaffold formation, chromatin fiber condensation
E) Scaffold formation, chromatin fiber condensation, supercoiling into nucleosomes

Question

Quizplus · Accepted Answer

The correct order of condensation levels for packaging metaphase chromosomes starts with supercoiling into nucleosomes, followed by chromatin fiber condensation, and finally scaffold formation. This sequence reflects the increasing complexity and organization required to compact DNA into metaphase chromosomes.
