One of the most common hypotheses that I hear with regard to possible non-coding DNA function is that it serves to protect genes against mutation. Junk DNA, according to this proposal, is there to…

Today's issue of Molecular Cell has two complementary papers on biological signal processing that look interesting (subscription required): "The Incoherent Feedforward Loop Can Provide Fold-Change…

Q.1 (i) A yeast artificial chromosome (short YAC) is a vector used to clone large DNA fragments (larger than 100 kb and up to 3000 kb). It is an artificially constructed chromosome and contains the…

Molecular biologists and mathematical models frequently don't mix well, especially when the molecular biologists in question were trained before the rise of genomics, back when most labs only needed…

Dear Mickey - How is life? Life is tough, says my friend. Do you agree? I wanted to write to you for a number of reasons. Believe it or not, people still remember that you turned 80 last year:…

Abnormally high levels of P-cadherin – an adhesion molecule that enables cells to bind together – occur in about a third of all breast cancers and are associated with poor prognosis. Portuguese…

Men could soon have the same control over their fertility that women have had since the 1960s, according to a new paper published in the December 2009 issue of The FASEB Journal. The authors of the…

Before you eat that next slice of pecan pie or second serving of mashed potatoes at Christmas dinner this year, you may want to think twice; those extra helpings could be even worse for your…

Gold maize was made by the ancient people of Peru, like the Moche Culture, because they ate corn. Corn, or maize (Zea mays L.) among scientists, is now one of our planet's top crops.…

Does genetic engineering have a role to play in developing sustainable agricultural systems? Many of the claims of the proponents of agricultural biotechnologies are being challenged by a coalition…
