Nuclear DNA influences variation in mitochondrial DNA By Allessandra DiCorato August 16, 2023 Breadcrumb Home Nuclear DNA influences variation in mitochondrial DNA Whole genomes from hundreds of thousands of people reveal new complexity in how the nuclear and mitochondrial genomes interact, which may influence how cells produce energy.
“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.
But as we pored over the photos and learned more about Sebastian’s journey, a far more interesting story emerged: one about the role of amateur science. ” Before the 19th century, virtually all science was amateur science. For the next 15 years, I hit my head against the wall trying to make science happen.
This method was more about serendipity than science. But as molecularbiology has advanced, so too has our approach to finding new drugs. In the early 20th century, the discovery process was largely random , focused on cytotoxic agents that kill cells by disrupting key cellular functions like DNA replication.
Not Just a Volcanic Eruption – Sinister Science, Too Spoiler alert! My knowledge of the field is only what I learned in high school earth science and watching Heather barf on the volcano, but I assume his comments are accurate. TMV is a common pathogen used in early molecularbiology research. BUT WAIT!!!
The genomic capabilities that were brought online for drug discovery (cheaper & faster next-gen DNA sequencing) did not diminish the need for biologists and translational scientists in target and patient selection, respectively. One final parallel to 2001.
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.
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.
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. Due to the nearly ubiquitous use of cloning in life science research, this lost time adds up. However, E.
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.
One thread that has run throughout it has been my passion for science as a lens for looking at the world. In particular, I love connecting science to daily life. Pfizer’s recent campaign around “ Science Will Win ” similarly appealed to the ethos of the power of science to help humanity. Remember life’s Central Dogma.
But “progress in science depends on new techniques, new discoveries and new ideas, probably in that order,” said Nobel Laureate, Sydney Brenner. That’s because proteins are made, in the laboratory, using synthetic DNA and cells; and DNA is expensive. It is the untouchable foundation of molecularbiology.
1 Present address: Functional Genomics and Metabolism Research Unit, Department of Biochemistry and MolecularBiology, University of Southern Denmark, Denmark. Summary: This paper discusses the use of a data science approach to synthesize current knowledge on the pharmacological implications of epigenetic regulation of gene expression.
When choosing my bachelor’s degree, the choice was between pursuing a career in biology or in computer science. Biology won that battle, and I pursued a bachelor’s and master’s degree in biochemistry and molecularbiology. In math and life and physical sciences, women now make up nearly half of the workforce.
NASDAQ:CDXC) today highlighted a new study published in The European MolecularBiology Organization Journal looking at the effect of nicotinamide riboside (NR) on maintaining telomeres, the protective regions at the end of DNA strands. is a science-based integrated nutraceutical company devoted to improving the way people age.
Rising from Research Scientist to Senior Scientist, I supported early-stage DD efforts within their Protein Science group, based in Cambridge, UK. My role involved generating and characterizing complex proteins critical for biological assay development, hit discovery, and structural biology.
The other powerful benefit is that our cell lines can become any of the cell types of the human body – these cells have within their DNA the capability to become any of the more than 200 human cell types which you might want to manufacture. This provides some regulatory advantages, and of course, significant cost advantages.
I have also learned a lot about the nuances of micropipettes that I would have never learned at school.” — Sheridan Moore , Research Associate Intern, Laboratory Sciences “My favorite part about interning at Altasciences is the potential for creating a long, meaningful career that I would be passionate about.
But “progress in science depends on new techniques, new discoveries and new ideas, probably in that order,” said Nobel Laureate, Sydney Brenner. That’s because proteins are made, in the laboratory, using synthetic DNA and cells; and DNA is expensive. It is the untouchable foundation of molecularbiology.
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.
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.
State-of-the-art R&D facility designed to foster collaboration across world-class science ecosystem Sustainable environmental engineering aligned to Company’s zero carbon future. Important discoveries have included Francis Crick and James Watson’s DNA advance in 1953, and Professor Sir John Gurdon’s work on stem cells in 2012.
From an article in Science : “After 6 months, the most promising varieties had their lignin content reduced by 49.1% in Science. They’ve just finished sequencing the patient’s genome, but they don’t have “DNA sorting” software. of which had reduced lignin levels and extra cellulose.

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. Anyone who has tried to engineer a cell knows how tedious it can be.

However, there are notable parallels both in the way the science was conducted and, at least for the genome project in the UK, the particular physical settings and sensibilities. Now I don’t want to claim too much. The background and impetus of the two projects were clearly very different. Left: Bletchley Park, photo by Einar H.
The only subject in school that held my interest was biology. As soon as I learned about DNA and RNA, I wanted to be a molecular biologist. I wanted to use molecularbiology to create drugs. Last stops at RNA My last roles in biotech were where my original passion began: DNA and RNA.
Molecularbiology, as the field came to be called 3 , pushed biology from an object of study, driven forward by gentleman scientists and precocious country clergymen, into a tool with which to solve urgent problems. Recombinant DNA technologies were invented in the 1970s.
DNA, proteins, polysaccharides, etc.). They are strongly oxidizing and, at high concentrations, are deleterious to cells damaging DNA, proteins and lipids, and eventually leading to cell death. Alberts B, How Cells Obtain Energy from Food, MolecularBiology of the Cell (4th ed.). nucleotides, monosaccharides, etc.),
Jensen, reported a much more detailed analysis of gas vesicles in the journal Science. Even after a half-century of molecularbiology research, scientists didn’t know until recently how gas vesicles physically trap gas while occluding water. By combining DNA from multiple organisms and inserting it into E.
But in the 1950s, at the dawn of molecularbiology, scientists gained a new appreciation for it after searching for organisms that were easy to work with and quick to grow. In 1952, when the famous Hershey-Chase experiment indicated that DNA—and not protein—was the source of genetic material, just 285 papers mentioned E.
A clinical genomicist harnesses team-based science to help rare-disease patients By Allessandra DiCorato January 7, 2025 Breadcrumb Home A clinical genomicist harnesses team-based science to help rare-disease patients Heidi Rehm convinced labs and scientists to work together and share data.
With the swift pace of scientific discoveries and a continuously deepening understanding of cancer biology, the oncology landscape is on the cusp of significant transformation. A strategic pivot back to DDR The need to refocus on DDR extends beyond science it is driven by an urgent necessity in patient care.
Enter epigenetics Broadly speaking, epigenetics refers to the system of proteins and marks that sits atop our genome a system that modifies gene expression, guides cell differentiation, and functionally organises our DNA. Progress in molecularbiology and translational science [Internet].
Also, some young women think that in order to work in STEM, they must be good at all four elements science, technology, engineering and math which isnt the case. Sabin earned her PhD in cellular and molecularbiology from the University of Pennsylvania.
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.”

He also posited the existence of a physical material to explain inheritance, which he called “elementen,” or “elements,” many years before nucleic acid had even been isolated 4 and more than 80 years before British biologists unveiled DNA’s structure and founded the field of molecularbiology.
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.
