3D structure of DNA


The puzzle of how 2 metres of double-stranded DNA is packaged into the nucleus of cell of the order of tens of microns, is a step closer to being solved. Professor Job Dekker of The University of Massachussets Medical School led the study which showed that DNA is tightly packed into a ball. The following link will lead you to a video explaining (in lay terms) the structure of the human genome, as explained by Professor Julian Parkhill: http://news.bbc.co.uk/1/hi/sci/tech/8294817.stm

If you'd like to learn more about the history of the discovery of DNA, its structure and how the DNA code is turned into protein, you should browse the DNAi website. This is an excellent educational resource run by Cold Spring Harbour Labs in the US. Further details can be found at http://www.dnai.org/.
