Study finds protein 'cement' that stabilizes the crossroad of chromosomes
Cell division is the basis of life and requires that each daughter cell receive the proper complement of chromosomes. In most organisms, this process is mediated at the familiar constricted intersection of ...
'Atomic chicken-wire' is key to faster DNA sequencing
An unusual and very exciting form of carbon - that can be created by drawing on paper- looks to hold the key to real-time, high throughput DNA sequencing, a technique that would revolutionise medical research ...
Centuries-old DNA helps identify origins of slave skeletons found in Caribbean
More than 300 years ago, three African-born slaves died on the Caribbean island of Saint Martin. No written records memorialized their fate, and their names and precise ethnic background remained a mystery. ...
Color-coading gene sequences in human cells
Ribose-seq identifies and locates ribonucleotides in genomic DNA
Ribonucleotides, units of RNA, can become embedded in genomic DNA during processes such as DNA replication and repair, affecting the stability of the genome by contributing to DNA fragility and mutability. ...
Bacteria become 'genomic tape recorders'
MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for ap ...
Researchers create unique graphene nanopores with optical antennas for DNA sequencing
(Phys.org) —High-speed reading of the genetic code should get a boost with the creation of the world's first graphene nanopores – pores measuring approximately 2 nanometers in diameter – that feature ...
Scientists make enzyme that could help explain origins of life
Mimicking natural evolution in a test tube, scientists at The Scripps Research Institute (TSRI) have devised an enzyme with a unique property that might have been crucial to the origin of life on Earth.
Charged graphene gives DNA a stage to perform molecular gymnastics
(Phys.org) —When Illinois researchers set out to investigate a method to control how DNA moves through a tiny sequencing device, they did not know they were about to witness a display of molecular gymnastics.
'Most famous wheat gene' found
Washington State University researchers have found "the most famous wheat gene," a reproductive traffic cop of sorts that can be used to transfer valuable genes from other plants to wheat.
Gibbon genome sequence deepens understanding of primates rapid chromosomal rearrangements
With the completion of the sequencing and analysis of the gibbon genome, scientists now know more about why this small ape has a rapid rate of chromosomal rearrangements, providing information that broadens ...
Coffee genome sheds light on the evolution of caffeine
Enzymes that help produce caffeine evolved independently in coffee, tea and chocolate, say scientists who have newly sequenced the coffee plant genome.
New material could enhance fast and accurate DNA sequencing
Gene-based personalized medicine has many possibilities for diagnosis and targeted therapy, but one big bottleneck: the expensive and time-consuming DNA-sequencing process.
Quasi-sexual gene transfer drives genetic diversity of hot spring bacteria
New work from a team including Carnegie's Devaki Bhaya and Michelle Davison used massive DNA sequencing of bacterial populations that grow in the hot springs in Yellowstone National Park to determine their ...
