Microbes are preferably suitable for joint biochemical as well as genetic research and studies and have been effective in providing evidence about the genetic code and the regulation of gene activity.

Researchers say they have created the first ever animal with artificial information in its genetic code.

ScienceDaily (May 9, 2011) - Mayo Clinic researchers have designed a new tool for identifying protein function from genetic code. A team led by Stephen Ekker, Ph.D., succeeded in switching individual genes off and on in zebrafish, then observing embryonic and juvenile development. The study appears in the journal Nature Methods.

By working with the simplest amino acids and elementary RNAs, physicists led by Rockefeller University's Albert J. Libchaber, head of the Laboratory of Experimental Condensed Matter Physics, have now generated the first theoretical model that shows how a coded genetic system can emerge from an ancestral broth of simple molecules.

Our genetic code is translated by two super-families of modern-day enzymes. Carter's research team created and superimposed digital three-dimensional versions of the two super-families to see how their structures aligned. Carter found that all the enzymes have virtually identical cores that can be extracted to produce "molecular fossils" he calls Urzymes-Ur meaning earliest or original. The other parts, he said, are variations that were introduced later, as evolution unfolded. These two Urzymes are as close as scientists have gotten to the actual ancient enzymes that would have populated the Earth billions of years ago.

"A new genetic biomarker that indicates an increased risk for developing breast cancer can be found in an individual's "junk" (non-coding) DNA, according to a new study featuring work from researchers at the Virginia Bioinformatics Institute (VBI) at Virginia Tech and their colleagues."

" 27.06.2000, FAZ #Schirrmacher Biologie.- Vor zehn Jahren, als das Genom weltweit gefeiert wurde, berichteten alle Zeitungen der Welt über dieses Ereignis. In Deutschland überraschte damals die "FAZ" mit einer ungewöhnlichen Idee: Sie brachte den biologischen Code ins Blatt: viele Seiten Buchstabengewirr aus A,T,G und C. Wer den Mitherausgeber und Feuilleton-Chef der "Frankfurter Allgemeinen Zeitung", Frank Schirrmacher, besuchen möchte, muss vorbei am Code des Lebens. Schon auf dem Flur: Eingerahmte Zeitungsseiten mit den vier Buchstaben A, T, G und C, vieltausendfach. Die Ausgabe stammt vom 27. Juni 2000, dem Tag als die Nachricht von der Entzifferung des menschlichen Genoms um die Welt ging. "

"Es gibt tatsächlich etwas, das genetische Integrität heißt. Bei Pflanzensorten, die schon existieren und die sich wenig verändern sollten, wenn man sie vermehrt. Das ist wichtig für den Erhalt der Biodiversität. In der Pflanzenzucht aber geht es immer um Veränderung. Sie ist das Fundament, auf dem sich bessere Sorten mit neuen Eigenschaften entwickeln lassen, eine größere Vielfalt. Da ist es vom Grundsatz her egal, ob man im Klostergarten Erbsen miteinander kreuzt, um dickere Schoten zu generieren. Oder ob man in einem Hightech-Labor mit Genscheren wie Crispr-Cas9 den Code im Erbgut der Hülsenfrüchte umschreibt. Keiner der Prozesse schützt die genetische Integrität der Erbse. Beide Vorgänge bringen das gleiche Ergebnis. Nur dass moderne Gentechniken schneller sind, Ressourcen schonen, weniger Kollateralschäden im Erbgut erzeugen."

"The rapid improvement in DNA sequencing has sparked a big data revolution in genomic sciences, which has in turn led to a proliferation of bioinformatics tools. To date, these tools have encountered little adversarial pressure. This paper evaluates the robustness of such tools if (or when ) adversarial attacks manifest. We demonstrate, for the first time, the synthesis of DNA which - when sequenced and processed - gives an at- tacker arbitrary remote code execution. To study the feasibility of creating and synthesizing a DNA-based exploit, we performed our attack on a modified down- stream sequencing utility with a deliberately introduced vulnerability. "
