PZ Myers on junk DNA.

PZ Myers, who apparently has a blog or something, gave a talk about junk DNA.

Favourite part: the Onion test followed by a Simpsons reference (at 37:00). Can’t ask for more than that! (Incidentally, PZ gets the onion test right — it’s about onions vs. humans AND onions vs. other onions; see also Larry Moran’s summary).

     The language and message could not be any clearer……PUBMEDScience. 2012 Sep 7;337(6099):1159, 1161.Genomics. ENCODE project writes eulogy for junk DNA…….Science 7 September 2012: Vol. 337 no. 6099 pp. 1159-1161 DOI: 10.1126/science.337.6099.1159NEWS & ANALYSISGENOMICS
    ENCODE Project Writes Eulogy for Junk DNAElizabeth PennisiThis week, 30 research papers, including six in Nature and additional papers published online by Science, sound the death knell for the idea that our DNA is mostly littered with useless bases. A decade-long project, the Encyclopedia of DNA Elements (ENCODE), has found that 80% of the human genome serves some purpose, biochemically speaking. Beyond defining proteins, the DNA bases highlighted by ENCODE specify landing spots for proteins that influence gene activity, strands of RNA with myriad roles, or simply places where chemical modifications serve to silence stretches of our chromosomes.This eulogy was issued 3 days ago. So forgive my passion but I’m still in mourning.

    Here is more evidence of ENCODES contribution to the progression of science concerning this so called junk. Question. What has PZ Myers done to contribute to these new findings? Answer. Absolutely nothing. In fact in telling these young people in the video above, that those who look for function, are only interested in job security he is doing more harm than good. Another words, lets just give up on research since we already know its junk. This is the same PZ Myers who told me to perform a certain sexual act on myself for simply asking a question. So please forgive the passionate tone in my post. I’m only human.The dynamic epigenomeNature Structural & Molecular Biology 20, 258 (2013) doi:10.1038/nsmb.2534Published online 05 March 2013Article toolsThe dynamic nature of functional information present in the genome—such as DNA methylation, histone modifications and chromatin organization—is beginning to be uncovered, along with the relationship between epigenomic patterning and developmental decisions or disease.Chromatin is a dynamic structure that must respond to myriad stimuli to regulate access to DNA. The epigenetic processes that modulate access to DNA in response to upstream signals include DNA methylation, covalent modification of histones, nucleosome remodeling, nuclear dynamics and chromatin interaction with regulatory noncoding RNAs. In recent years epigenetic processes have been extensively studied at a mechanistic level, but their dynamic nature in genomes is only beginning to be uncovered—thanks in part to herculean efforts by the Encyclopedia of DNA Elements (ENCODE) Consortium and others to generate hundreds of genome-wide datasets to map the human ‘epigenome’ and that of other organisms. Genome-wide studies are also being extended to analyze the relationship between epigenomic patterning and developmental decisions or disease, and the crosstalk between different epigenetic processes. In this issue, we present a special Focus on Epigenetic Dynamics………
