😊Chromatin is basically a DNA in the nucleus which is the uncondensed form of chromosomes. When a DNA replicates itself, it produces two chromatids which are joined together at centromere. Both chromatids are genetically identical.
😊When the cell is not dividing, the strands of DNA are called as chromatin and in mitosis after replication, the chromosomes have two chromatids.
😊Chromatin is the indistinguishable mass of DNA molecules whereas chromatids are a part of chromosome attached to it with a centromere.
