    Synthetic DNA Created

    Synthetic DNA Created, EVOL-VES on Its Own

    Christine Dell'Amore

    Published April 19, 2012

    Step aside, DNA—new synthetic compounds called XNAs can also store and copy genetic information, a new study says.


    And, in a "big advancement," these artificial compounds can also be made to E-VOLE in the lab, according to study co-author John Chaput of the Biodesign Institute at Arizona State University. (See "Evolution vs. Intelligent Design: 6 Bones of Contention.")


    Nucleotides, the building blocks of DNA are composed of four bases—A, G, C, and T. Attached to the bases are sugars and phosphates. (Get a genetics overview.)

    First, researchers made XNA building blocks to six different genetic systems by replacing the natural sugar component of DNA with one of six different polymers, synthetic chemical compounds.

    The team—led by Vitor Pinheiro of the U.K.'s Medical Research Council Laboratory of Molecular Biology—then ****ed enzymes, called polymerases, that can make XNA from DNA, and others that can change XNA back into DNA.

    This copying and translating ability allowed for genetic sequences to be copied and passed down again and again—artificial heredity.

    Last, the team determined that HNA, one of the six XNA polymers, could respond to selective pressure in a test tube.

    As would be expected for DNA, the stressed HNA EV0LVED into different forms.

    Civil rights groups release a statement criticizing the movement against high-stakes testings. An education advocacy group release a response, saying the civil rights groups are wrong. Read them both.

    This new advancement will bring much convenience to the related researches first.

    Re: Synthetic DNA Created

    Your DNA, like that of everything else on the planet, is made of four nucleotides: A, C, G, and T. These are like a blueprint that your body reads to produce 20 different amino acids, which combine to make up the proteins that enable everything your body does, like repairing damaged cells or breaking down food.Last year, biotech startup Synthorx announced that it had pushed the limits of biology by adding new building blocks to a bacteria’s genetic code. Now they’ve gone a step farther: those engineered bacteria have created a well-studied protein that has an added function, according to a press release the company issued yesterday. This could be the first step towards the discovery of new, more effective drugs and vaccines.Synthorx added two more nucleotides, X and Y, to a bacteria’s DNA. These combine with the other four to make up to 172 different amino acids—over eight times the 20 commonly found in nature. These can combine to make an enormous number of proteins never before seen on Earth.

    Umm, that looks familiar?

    Oh, found it.

    You seem to have verbatim copied your post without citing the source.
    Plagiarize much?

    Reference article for the (above) Popular Science article;
    https://www.technologyreview.com/s/5...fe-seeks-work/

    I would also point out that neither of the above cited articles are from a Scientific Journal.
    In other words, this work has not as yet been published for peer-review, at least AFAIK.
    Ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science. -C. Darwin

    WHoa that video of DNA was crazy man. I wonder if they are going to mutate it with animals and have hybrid animal babies
