What stage is the mitotic spindle visible?
Chromosomes are easiest to see when they are condensed(coiled and supercoiled, so that they become short and fat).They are at their most condensed from late prophase through to early telophase, in either mitosis or meiosis.Their visibility also depends on suitable microscopic technique, including the use of an appropriate stain, such as acetocarmine.

How we can use acetocarmine to stain the onion root tip cells?
take the root tip (about 1 cm )and put it in dil. HCL solution for ten min. take the tip out and put in acetocarmine stain for 1min. take out the root put it in water bto remove extra stain .
What is acetocarmine?

Will sanding the old stain off a maple piece of furniture work if wanting to stain a new color?
In order to stain your filing cabinet a new color you will have to prepare it first. You will have to strip the old finish off and then sand the wood and prime it so it is ready to accept the new color. If you don't want to do all of the prep work you could look for a primer paint and then an oak color and try painting over it, but it will not look nearly as nice as it will if you strip it, prepare it and stain it.
