“Bill Studier’s development of T7 phage RNA polymerase for use in preparing RNA templates for multiple uses in research labs worldwide has been a truly revolutionary technical advance for the entire field of molecularbiology,” said Joan Steitz, the Sterling Professor of Molecular Biophysics and Biochemistry at Yale University.
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.
.” The explanation continues, and here’s where it ceases to make sense, to anyone who knows anything about DNA, genes, and genomes. TMV is a common pathogen used in early molecularbiology research. A plant genome consists of DNA, and NOT pieces of 2,4-D, which is a completely unrelated organic acid.
Phage have been of interest to scientists as tools to understand fundamental molecularbiology, 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.
billion bases of DNA which, if unfurled, would extend for more than 100 meters—taller than the Statue of Liberty. billion bases of DNA, the human genome measures just 2 meters in length when stretched end-to-end. Credit: Oriane Hidalgo Per the book Cell Biology by the Numbers , each base pair of DNA occupies 1 nm 3 of space.
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.
STING is primarily on the lookout for DNA, which can indicate either a foreign invader such as a virus or damage to the host tissue or cell. Once it detects DNA, it relocates to the Golgi body, where it begins to activate proteins that turn on genes required for interferon production. Paper Cited Liu B, Carlson R, et al.
What are the key findings of Circio’s in vivo proof-of-concept for its circVec circular RNA platform technology compared to conventional mRNA-based expression with DNA vectors? DNA vectors in mouse models? Circular RNA (circRNA) has two major advantages versus mRNA in a vector-expression context.
They’ve just finished sequencing the patient’s genome, but they don’t have “DNA sorting” software. billion units of DNA code are transcribed into more than a hundred volumes, each a thousand pages long, in type so small as to be barely legible.” You can read all of them here. From Ling B et al.

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 molecularbiology instrumentation such as Bio-Rad’s ddPCR system, the NanoDropTM One spectrophotometer, and dedicated polymerase chain reaction (PCR) chambers.
Notes on Progress is a monthly roundup of papers and ideas about biology and the future. “The recombinant DNA breakthrough has provided us with a new and powerful approach to the questions that have intrigued and plagued man for centuries. Biology is a Burrito. A new base editor to edit mitochondrial DNA.
DNA sequences are designed on a computer, and it takes a dozen or more clicks to change a single nucleotide. DNA sequences are also checked by hand, so it’s easy to make a mistake. The tool outputs a DNA sequence that encodes all the required enzymes. A phage is a virus that infects bacteria.

From her early fascination with biology to her current role at Regeneron , she has worked on groundbreaking projects aimed at improving the safety, efficacy and durability of gene therapies. My fascination with biology and the natural world began early in life, growing up as a lover of animals and nature.
By Matthew Cobb The Central Dogma is a linchpin for understanding how cells work, and yet it is one of the most widely misunderstood concepts in molecularbiology. Many students are taught that the Central Dogma is simply “DNA → RNA → 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 molecularbiology. 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.
