We have studied the site of deposition of newly synthesized histone. It appears to be randomly distributed over the chromosomal material and does not become associated specifically with immediately post-replicational DNA, nor is it deposited in discrete continuous regions distal to the sites of DNA synthesis. The newly synthesized DNA, however, rapidly acquires a complement of chromosomal proteins; presumably, preexisting histones must migrate to become associated with post-replicational DNA.
我们已经研究了新合成组蛋白的沉积位点。它似乎随机分布在染色体物质上,并不与复制后立即形成的DNA特异性结合,也不是沉积在DNA合成位点远端的离散连续区域。然而,新合成的DNA会迅速获得一组染色体蛋白;据推测,预先存在的组蛋白必须迁移才能与复制后的DNA结合。
