Biologists' Discovery May Force Revision of Biology Textbooks: Novel Chromatin Particle Halfway Between DNA and a Nucleosome


These pre-nucleosomes, the researchers say, are converted into nucleosomes by a motor protein that uses the energy molecule ATP.

"The discovery of pre-nucleosomes suggests that much of chromatin, which has been generally presumed to consist only of nucleosomes, may be a mixture of nucleosomes and pre-nucleosomes," said Kadonaga. "So, this discovery may be the beginning of a revolution in our understanding of what chromatin is."

"The packaging of DNA with histone proteins to form chromatin helps stabilize chromosomes and plays an important role in regulating gene activities and DNA replication," said Anthony Carter, who oversees chromatin grants at the National Institute of General Medical Sciences of the National Institutes of Health, which funded the research. "The discovery of a novel intermediate DNA-histone complex offers intriguing insights into the nature of chromatin and may help us better understand how it impacts these key cellular processes."

1. I did not understand a word of that............

except the small ones

5. Basically it says that stuff is more complicated and confusing than they thought it was

But they are working on sorting it out.

9. That is good ....... better them than me

2. Cool.

Thanks for link.

3. I think he's basically saying......

...apes evolved from the Bush family. But I could be wrong.

4. Only the most advanced biology textbooks ...

no change to high school textbooks. They don't go into that much detail.

6. Very Cool! better understand of Gene manipulation and gene therapy's are on the horizon

Good article

[ohheckyeah]

7. Like I every understood any of that stuff in the first place.

Revise away.

8. Yep. Sounds like histone proteins. Always slinking around DNA, looking to form chromatin. Bastards.
