- To be exact, DNA is coiled up around proteins called histones, which are then condensed into strands of chromatin, which are then coiled up even more to make tightly packed units of DNA called chromosomes, which kind of look like worms.
確切地說，DNA盤繞在稱為組蛋白的蛋白質周圍，組蛋白凝結成染色質鏈，染色質鏈再盤繞成更緊密的DNA組織、部門，稱為染色體，看起來有點像蠕蟲。
