Certain CRISPR components can add short DNA sequences from the genomes of defeated viruses into the bacterium’s own genome, creating a type of protective “memory.” If the same virus invades the cell a second time, the gRNA’s spacer sequence will bind to the matching viral DNA sequence, then be cut by the Cas protein.

I’ve chosen these two because I think they are the linchpin by which we’ll be able to build broadly useful AI models for cell and molecular biology. Synthesizing a single human protein-coding gene costs several hundred dollars and even a simple PCR machine (used for amplifying DNA) costs between $1,500 and $50,000.

To celebrate the new issue, we are also releasing new merchandise (custom-designed shirts, hats, and posters) and hosting a biology trivia night in San Francisco on July 23 ! The event hosts will provide snacks and drinks, and the winning teams will get signed copies of our DNA books and free hats. Please RSVP to join.

Phage have been of interest to scientists as tools to understand fundamental molecular biology, as vectors of horizontal gene transfer and drivers of bacterial evolution, as sources of diagnostic and genetic tools, and as novel therapeutic agents. Its presence elsewhere would indicate something is wrong.

PJ: At Altasciences, we have a range of leading-edge platforms that include ligand binding assays (LBA), NAb, TAb, flow cytometry, and ELISpot, as well as on-site molecular biology instrumentation such as Bio-Rad’s ddPCR system, the NanoDropTM One spectrophotometer, and dedicated polymerase chain reaction (PCR) chambers.

However, they plod along as they clone plasmids—the loops of DNA that biologists use to manipulate and study organisms—because propagating them relies, in part, on the pace at which cells grow and divide. Most medicines, including insulin and semaglutide (the weight loss drug), are made using DNA cloning. However, E.

doi: 10.2210/rcsb_pdb/goodsell-gallery-048 The Virus that Cures It’s been over 25 years since the science magazine Discover first ran an extraordinary article about how a long-forgotten medical treatment, used in the former Soviet country of Georgia, could save us from the growing threat of untreatable, drug-resistant infections.
