Grain traits traced to ‘dark matter’ of rice genome
by
•Research finds that a sizeable amount of domestication-related changes in rice reflects selection on traits that are determined by a portion of the genome that does not transcribe proteins. …read more Source:: Science
The secret to a long life? For worms, a cellular recycling protein is key
by
•Scientists have shown that worms live longer lives if they produce excess levels of a protein, p62, which recognizes toxic cell proteins that are tagged for destruction. The discovery could …read more Source:: Science
First cells may have emerged because building blocks of proteins stabilized membranes
by
•Scientists have discovered that the building blocks of proteins can stabilize cell membranes. This finding may explain how the first cells emerged from the primordial soup billions of years ago: …read more Source:: Science
Genes that evolve from scratch expand protein diversity
by
•A new study challenges one of the classic assumptions about how new proteins evolve. The research shows that random, noncoding sections of DNA can quickly evolve to produce new proteins. …read more Source:: Science
