WebJan 3, 2024 · Chromosomes and chromatin are a uniquely eukaryotic association of DNA with more or less protein. Bacterial DNA (and prokaryotic DNA generally) is relatively ‘naked’ – not visibly associated with protein. The electron micrograph of an interphase cell (below) reveals that the chromatin can itself exist in various states of condensation.
WebWhen a cell divides, the chromatin fibres condense into long threads and form chromosomes, which are rod-like structures. The chromosomes, like the chromatin, contain DNA, which is essential for protein synthesis.
