HIV inserts into human genome using a DNA-associated protein

...tain RNA in their particles. They enter a cell and convert RNA into DNA by the enzyme reverse transcriptase and then integrate that DNA copy into the DNA of the host, using the integrase enzyme. The new viral particles are made by transcription of the viral genome, as with any cellular genes. If the cell div...

Study provides insight into cellular defenses against genetic mutation

...ing protein shortages." Researchers may be able to convert mRNA quality control from NMD over to a more flexible system that "overlooks" flaws, and provides more templates for building functional proteins. Genetic Decision Maker For two decades, researchers have made intuitive leaps in the understandin...

Prions rapidly 'remodel' good protein into bad, Brown study shows

... a small amount of prion-state protein can rapidly convert healthy protein into a pathogenic form." ...

Oceans turning to acid from rise in CO2

...arine plants soak up CO2 as they breathe it in and convert it to food during photosynthesis. Organisms also use it to make their skeletons and shells, which eventually form sediments. With the explosion of fossil-fuel burning over the past 200 years, it has been estimated that more than a third of the human-...

Researchers find ways to turn manure into power

...th manure as a fertilizer and have studied ways to convert it into energy, but this latest push of legislatio..." Sweeten said. "The question becomes, how do you convert biomass into energy?" he said. The solid feedlot waste presents a different challenge than the liqu...

Green diesel: New process makes liquid transportation fuel from plants

...ays Dumesic. "Each molecule of hydrogen is used to convert each carbon atom in the carbohydrate reactant to an alkane. It's a very high yield. We don't lose a lot of carbon. The carbon acts as an effective energy carrier for transportation vehicles. It's not unlike the way our own bodies use carbohydrates to...

Cells direct membrane traffic by channel width

...urally they are similar. Researchers have tried to convert a water channel to a glycerol channel, or the other way around, by mutating amino acids that line the pore of the channel, but they have failed." The E-coli proteins studied were AqpZ, a water channel, and GlpF, a glycerol channel. Side-by-side in c...

Hidden sponges determine coral reef's nutrient cycle

...nutrient cycle due to their incredible capacity to convert enormous quantities of organic plankton into inorganic material. The results from Scheffers' research have been made available to the personnel from the Marine under water park of Curaao and have been presented to the local government. ...

UCLA researchers identify key enzyme linked to childhood blindness

...lls, looking for a gene that caused these cells to convert vitamin A into 11 cis retinol. The researchers are now studying the effects on retinoid isomerase activity of specific disease causing mutations in the RPE65 gene, which should provide more data on the cause of Leber congenital amaurosis and on how ...

Clearing jams in copy machinery

...ases -- the building blocks that make up DNA -- to convert the now-single-stranded templates into two new duplex DNA molecules. The new research shows that two different DNA polymerases, the high fidelity Pol III replicase and the low fidelity Pol IV, coordinate their action to cross obstacles encountered i...

Carnegie Mellon cyLab researchers work to develop new red tide monitoring

...negie Mellon researchers to devise a way to simply convert harmful algae data into an image field that can be easily accessed to map out the deadly algae's location and where it may travel. The new software is designed to incorporate multiple computer vision algorithms and the domain knowledge from NOAA scie...

Pollution-eating bacteria produce electricity

...ey can consume. That means that these bacteria can convert a large number of different food sources into electricity," says Milliken. "The technology could be used to assist in the reclamation of wastewaters, thereby resulting in the removal of waste and generation of electricity." Another unique characteri...

Modification of program enables prediction of gene transcription

... of exons in both parts of the gene, we're able to convert a blind guessing game to a multiple choice question ?is it a UTR exon or a protein-coding exon? These kinds of questions are easier to answer now." ...

Microbe has huge role in ocean life, carbon cycle

...try. Photosynthesis is a process used by plants to convert sunlight energy into organic molecules, creating the foundation of the food chain and producing oxygen. About half of photosynthesis and the resulting oxygen on Earth are produced by algae in the ocean, and microbes like SAR11 recycle organic carbon ...

MERIS monitoring tracks planetary photosynthesis levels

...ant life uses the process called photosynthesis to convert incoming sunlight into chemical energy, along the way producing all the oxygen we breathe. The fraction of incoming solar radiation useful for photosynthesis that is actually absorbed by vegetation ?a value known as the Fraction of Absorbed Photo...

Tagging pathogens with synthetic DNA 'barcodes'

...ortant, Luo said. For convenience, a computer can convert the subtle differences in light intensity between, say 4G1R and 3G1R, into "pseudo colors," perhaps making one appear as orange and the other as pink, to make the difference clear to a human eye. The researchers point out that the nanobarcode detect...

Researchers Discover That Microbes Can Produce Miniature Electrical Wires

...metals or petroleum. They also have the ability to convert human and animal wastes or renewable biomass into electricity. To carry out these processes, Geobacter must transfer electrons outside the cell onto metals or electrodes. This new research provides an explanation of how this can happen. Previous stu...

Researchers extend mouse lifespan by protecting against free radicals

...tudy on catalase, an enzyme in the body that helps convert hydrogen peroxide into water and oxygen. Hydrogen peroxide is a waste product of metabolism and it can be a the precursor of free radicals that can damage the cell. The damage can in turn lead to more flaws in the cell's chemical processes, making a ...

It's electric: Cows show promise as powerplants

...one California farmer reportedly spent $280,000 to convert his operation to a methane digester system. "Methane still needs to undergo combustion, which creates issues with energy efficiency," said Hamid Rismani-Yazdi, the study's lead author and a graduate student in food, agricultural and biological engin...

Bioinformatics reveals new gene regulation system

...or ribonucleotide reductase enzymes. These enzymes convert the ribonucleotide building blocks of RNA into the deoxyribonucleotides used to build DNA. This conversion is critical for duplicating a bacterium's entire genome before it divides to reproduce. The search revealed a conserved palindromic sequence o...
