Why the genome must be a product of intelligent design

Watch the human genome fold itself in four dimensions:

By removing and then adding this protein, called cohesin, researchers made specific DNA loops that disappear and then reappear, they report this month in Cell. But cohesin really only affects looping that brings genes on the same chromosome into contact. A second, still-undefined mechanism seems to bring genes from different chromosomes together, the team notes.

Notes:

Will we ever… reveal all the secrets of life from DNA?:

Our metaphors let us down. Science writers like to compare the genome to a textbook or a blueprint. That conveys the fact that it stores information, but glosses over its buzzing, dynamic nature – proteins docking on and off to control the activity of genes, huge stretches of DNA that fold and unfold to reveal or hide their sequences,,, jumping genes that copy themselves and hop throughout the genome… None of our information stores – not sheet music, not recipe books – are this intricate.More.

Genes and Organisms: Improvising the Dance of Life:

Excerpt: packing DNA into a typical cell nucleus is like packing about 24 miles of very thin, double-stranded string into a tennis ball, with the string cut up (in the normal human case) into 46 pieces, corresponding to our 46 chromosomes.

To locate a protein-coding gene of typical size within all that DNA is like homing in on a one-half-inch stretch within those 24 miles. Or, rather, two relevant half-inch stretches located on different pieces of string, since we typically have two copies of any given gene. Except that sometimes one copy differs from the other and one version is not supposed to be expressed, or one version needs to be expressed more than the other, or the product of one needs to be modified relative to the other. So part of the job may be to distinguish one of those half-inch stretches from the other. …

the cell, by managing the shifting patterns of the chromatin infrastructure within which DNA is embedded, brings our chromosomes into movement on widely varying scales. These include large looping movements that put particular genes into connection with essential regulatory sequences and with other, related genes (that is, with other one-half inch stretches of our “24 miles of string in a tennis ball”). …

… There is no neatly predefined path to follow once the cell has located the “right” half inch or so of string, or once it has done whatever is necessary to bring that locus into proper relation with other chromosomal loci participating in the same “dance”. … the overall picture of gene expression is one of unsurveyable complexity in the service of remarkably effective living processes. …

A decisive problem for the classical view of DNA is that “as cells differentiate and respond to stimuli in the human body, over one million different proteins are likely to be produced from less than 25,000 genes”.30 Functionally, in other words, you might say that we have over a million genes. … (Stephen L. Talbott, Nov. 10, 2015)

    NEWS,

    did you post this as an attack on ID theory? Such as it is?

    “Our metaphors let us down.”
    “None of our information stores- not sheet music, not resipe books- are this intricate.”

    It seems the whole ID edifice, that of ‘information theory’, and gene stored information, is undermined by this work.

    Sure, they say the genome and its functions are bewilderingly complex, but they also say, don’t think of it as information; as atheists we already new human interpretations of nature were weak, after all, look at the Bible’s childish metaphors and tales.

    A giant flood; a talking snake; a human eating whale; come on what next? ‘Information’, in a biologically replicating molecule? Perhaps the molecule replicates by natural forces, and does not do so for any percieved human reason, other than it can not help it self; nature you see!

    Not even close. Genes still code for proteins. And they are saying the information is much more intricate than what we try to compare it to.

    Was it the title of the OP that gave it away?

    Are you taking up comedy now?

    Are you referring to this statement?

    None of our information stores – not sheet music, not recipe books – are this intricate.

    Because it affirms that DNA is an information store.

    All one has to do is simply look at the fundamental structure of the genome, such as nucleotide…

    It easy to say that genome didn’t have to be designed and intelligently assembled if you never had to the real work…

    Craig Venter and his team, including Nobel Prize laureate, certainly know a thing of two about designing and assembling an “artificial genome”…

    In fact, chemically creating and assembling nucleotides for the mycoplasma’s “synthetic genome” was so difficult, that Venter’s team had to use nucleotides from fish and had yeast assemble it for them into the mycoplasma genome…

    Unfortunately, the Media have omitted this very important information because most likely they didn’t even know those pretty important facts or it would make great news… Pity…
