QUESTION 7 2 poir What determines the characteristic shape of metaphase chromosomes when viewed using light microscopy O DNA phosphate backbone and euchromatin O Scaffolding proteins on the nuclear lamina O catananes OZ-DNA which forms during low salt conditions

Answer 1

Answer :

Metaphase stage of cell division is marked by visible intact chromosome. The chromosome aquire specific shape due to scaffolding proteins on nuclear lamina. The scaffolding proteins are necessary for compaction of chromosome into specific shape.

Thus, the correct choice should be:

(b) scaffolding proteins on the nuclear lamina.
