DNA and RNA molecules are also built from exclusively right-handed nucleic acids. Across the tree of life, organisms strictly require exactly one of the two chiral forms of their molecular building blocks — amino acids, nucleotides of RNA and DNA. 4 As far as we know, right-handed proteins never occur naturally.

Thanks to decades of progress in molecular sequencing technologies, it is simple to read out the order of nucleotides in a DNA sequence, for example, or to quantify messenger RNAs as they are made by a cell. The ATP synthase “bead” experiment was part of a 2001 study published in the journal Nature.

The most groundbreaking cancer drug approval was for Gleevec , with a mere 3-month trajectory at FDA before its approval in 2001. The tool detects cancer cells and pinpoints the origin of the tumor, as well as identifying and assessing gene and DNA patterns to predict patient outcomes and treatment responses.

“RFLPs” are sites in a DNA sequence where a bacterial enzyme, called a restriction enzyme, cuts. See The Age of the Pangenome Dawns , here at DNA Science from a few months ago.) As the first genomes were being sequenced, researchers began identifying the sites where the 4 DNA bases vary among individuals.

A “DNA damage checkpoint” rests the cell cycle while special proteins repair damaged DNA. After passing safety tests, Gleevec worked so well that it set a new record for drug approval—10 weeks, on May 10, 2001. The post How Targeted Cancer Drugs Disrupt the Cell Cycle appeared first on DNA Science.

And whereas it used to be costly for breeders to select for traits beyond the needs of their industry, the falling costs of advanced genomic selection techniques—breeding using DNA sequence data—make it increasingly fast and feasible. By contrast, knocking out FAAH makes the animals retain enough pain-signaling to avoid damage.

“Hazards of Mouth Pipetting” The micropipette, an instrument favored by researchers around the world to measure and move liquids from one container to another and used for everything from forensic analysis to DNA sequencing, was invented by an obscure, 32-year-old German postdoc after a particularly productive two-day tantrum.

Because the FDA has asserted since 2001 that modification of human embryos would require its permission, this effectively bans even the testing of such technology in the U.S. while it proceeds elsewhere.
