Now researchers at the Broad Institute of MIT and Harvard have used cutting-edge continuous laboratory evolution and engineering methods to develop improved versions of the gene-editing tool. Reverse transcriptase proteins that copy RNA templates into strands of DNA are found naturally in all plant and animal cells and in many viruses.
The automation of processes, workflows, and data enables laboratories to reduce downtime, increase scalability, and optimize efficiency. Automation provides the time and space for biotech R&D laboratories to focus on innovations and improvements, which is crucial to a laboratory’s success.
Allison Berke makes the case for real-time DNA sequencing and AI tools to detect pathogens before they spread widely. Reading DNA The first step in detecting a novel pathogen is recognizing it as an anomaly amidst a noisy background of other material. After copying the DNA to form a big pool, each piece is sequenced.
DNA topoisomerase IIβ (TOP2β/180; 180 kDa) is a nuclear enzyme that regulates DNA topology by generation of short-lived DNA double-strand breaks primarily during transcription. TOP2β/180 can be a target for DNA damage-stabilizing anticancer drugs, whose efficacy is often limited by chemoresistance.

Caruthers was announced as the winner in June for his development, in 1981, of an efficient, automated technology for synthesizing DNA.
Working at the famed Pasteur Institute, the duo began by figuring out how best to culture mycobacteria — a seemingly simple, but essential first step, given how no one at the time had yet come up with an effective way of growing these bacteria in the laboratory. Many more could emerge as machine learning tools improve.
Astronauts face a myriad of ongoing and long-term risks that include reduced muscle mass and bone density loss, accelerated cancer cell metastasizing, and DNA damage. The primary hazards in space, such as microgravity and cosmic radiation, have serious implications for human health.
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.
Brian Wang (co-founder of the nonprofit Panoplia Laboratories ) outlines his approach to making broad-spectrum antivirals.

Beyond simply backing great science (separating the wheat from the chafe), setting a company up properly is critical, and early choices can get locked into the DNA of the company. Some continue to do so today, unfortunately, but there appears to be less of it happening. Second, great teams of truly experienced leaders are scarce.
Unlike gene editing, this “epigenetic” editing does not modify the underlying DNA sequence, but it should switch the gene off permanently, which means that this could be a one-time treatment. Like Cas9, ZFPs can serve as guide proteins to direct the tool to a target site in DNA.
The underlying assumption of most gene therapy procedures, irrespective of the disease being targeted, is that restoration of a wild-type DNA sequence will alone be sufficient to normalise the phenotype of the individual. Surely, then, a correct set of DNA plans will ensure a correctly functioning cell?
Whether it is determining concentrations of molecules like proteins or DNA, looking at enzyme kinetics for crucial reactions, or measuring something as fundamental as cell growth, you will find references to absorbance or optical density measurements. Optical density is also widely used for many scientific applications.

However, some groups will decide to complete this stage within their own laboratories. After binding, the transposase enzyme will excise the flanked section of DNA (termed the transposon) and insert it into sites in the genome at specific target sequences. We talk about personalised medicine; how about personalised host cell lines?
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.
Gene therapy requires DNA and/or RNA delivery and analysis, and while most ongoing research involves therapies being delivered in vivo via adeno-associated viral (AAV) vectors, other in vivo delivery methods are on the rise. The process utilizes short synthetic DNA fragments called primers to choose a section of the genome to be amplified.
Researchers from the Laboratory of Bacteriology at The Rockefeller University have now found that bacteria sense phages by a defensive response named CBASS (cyclic oligonucleotide-based antiphage signalling system) which detects viral RNA. Its presence elsewhere would indicate something is wrong. But what, exactly?”
In addition, we have concluded that the gene product is an apicpolast RNA polymerase sigma factor because of the localisation of the gene product, ApSIGMA, in the apicoplast interaction with apicoplast promoter DNA sequences, and the activity of an ApSIGMA- E.coli _RpoS chimeric sigma factor protein.
