“Junk DNA” and the Molecular Basis of Cell Identity

Once thought to be “junk,” or functionless vestiges of once-protein-coding-genes which have, through the course of evolutionary history, mutated to a state of non-functionality, the research documents that these lincRNAs have an extremely important — even crucial — role with respect to the determination of cellular identity.

Craig Venter’s Typo Shows Poor Design is Still Design

Forbes.com is reporting that Craig Venter’s “synthetic” bacterial chromosome contains a “genetic typo.” Molecular biology has ascribed a letter to each amino acid. Venter and his team imported DNA sequences into the chromosome–called watermarks–that coded for amino acids which ‘spelled out’ sentences in the chromosome. But they got one sentence wrong. As the article reports: The synthetic DNA also included a quote from physicist Richard Feynman, “What I cannot build, I cannot understand.” That prompted a note from Caltech, the school where Feyman taught for decades. They sent Venter a photo of the blackboard on which Feynman composed the quote -and it showed that he actually wrote, “What I cannot create, I do not understand.” “We agreed what was on Read More ›
