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.
Scientists complete chromosome-based draft of the wheat genome
Several Kansas State University researchers were essential in helping scientists assemble a draft of a genetic blueprint of bread wheat, also known as common wheat. The food plant is grown on more than 531 ...
Design of self-assembling protein nanomachines starts to click
(Phys.org) —A route for constructing protein nanomachines engineered for specific applications may be closer to reality.
Extensive cataloging of human proteins uncovers 193 never known to exist
Striving for the protein equivalent of the Human Genome Project, an international team of researchers has created an initial catalog of the human "proteome," or all of the proteins in the human body. In total, ...
Breakthrough shows how DNA is 'edited' to correct genetic diseases
An international team of scientists has made a major step forward in our understanding of how enzymes 'edit' genes, paving the way for correcting genetic diseases in patients.
