What is the difference between chromatin fiber and chromosomes?
Chromatin is the usual form of the DNA in a cell. It has the appearance of grainy blobs in the nucleus because it is too thin to be seen as actual strings. Imagine unwinding a whole ball of kite string and just having a massive heap of string on the floor. That’s chromatin. Chromosomes are formed in prophase of mitosis or meiosis. The chromosomes are made out of chromatin that is wound up around special proteins. The would up chromatin coils more and more until it forms identifying thick strands … those are the chromosomes. Chromosomes are only seen during mitosis.
