Question

what do you need to do in order to condense the chromatin and get the ok! button to appear? once you have done this, move on. click on each chromatin double click on the nuclear membrane drag the cell membrane to the middle of the cell

Explanation:

In a cell - related simulation or educational context, clicking on each chromatin is a common action to initiate the condensation process of chromatin. Double - clicking on the nuclear membrane is more related to actions like nuclear envelope breakdown (in some cell cycle simulations) rather than chromatin condensation. Dragging the cell membrane has no direct relation to chromatin condensation.

Answer:

click on each chromatin
