【英语时差8,16】基因的组织方式

（单词翻译）

I know that every cell in my body has a copy of my DNA¹ packed into its nucleus². And I also know that if I could somehow unravel³ the DNA from a single cell, it would be about six feet long. So my question is, is DNA jammed into the nucleus in a sort of random⁴ knot? D:Great question! Scientists know that DNA is able to fit into such a small space because it’s wound tightly around proteins. But scientists also thought that DNA was randomly⁵ packed in. Researchers at MIT have figured out that that’s not true.The way that DNA is packed in a cell nucleus is more organized. Y:How so? D:Well, the researches aren’t certain–they’ve only discovered clues. But based on what they’ve found, it seems that parts of DNA that are being transcribed⁶ or copied are located together. Y:Cool.But so what?I don't mean to seem on curious,but what is it matter whether we know how DNA is organized？ D:It matters because the way that DNA is organized affects how it works. In fact, other studies have shown that genes⁷ that are near each other may affect one another. They can even switch each other on and off. Y:I see. Like most physical objects,I guess that what DNA does depends at least a part on how its part fit together. D:Right.And the more scientist know about those parts,the better they understand how thw whole thing actually works.
