Research uncovers new exception to decades-old rule about RNA splicing
There are always exceptions to a rule, even one that has prevailed for more than three decades, as demonstrated by a Cold Spring Harbor Laboratory (CSHL) study on RNA splicing, a cellular editing process. The rule-flaunting ...

Defect in transport system causes DNA chaos in red blood cells
Within all our cells lies two meters of DNA, highly ordered in a structure of less than 10 micro meters in diameter. Special proteins called histones act as small building bricks, organising our DNA in this structure. Preservation ...

Genes linked to cancer could be easier to detect with liquid lasers
Using a liquid laser, University of Michigan researchers have developed a better way to detect the slight genetic mutations that might predispose a person to a particular type of cancer or other diseases.

Aging human bodies and aging human oocytes run on different clocks
Reproductive and somatic aging use different molecular mechanisms that show little overlap between the types of genes required to keep oocytes healthy and the genes that generally extend life span, according to Coleen Murphy, ...

When inflexibility is counterproductive: Mechanism of UV-induced DNA Dewar lesion revealed
Excessive exposure to ultraviolet (UV) radiation of sunlight can result in skin damage and may even induce skin cancers. Irradiation with UV light causes mutations in the DNA, which can interfere with or even inhibit the ...

Surprise role of nuclear structure protein in development
Scientists have long held theories about the importance of proteins called B-type lamins in the process of embryonic stem cells replicating and differentiating into different varieties of cells. New research from a team led ...

Life-history traits may affect DNA mutation rates in males more than in females
For the first time, scientists have used large-scale DNA sequencing data to investigate a long-standing evolutionary assumption: DNA mutation rates are influenced by a set of species-specific life-history ...

Non-independent mutations present new path to evolutionary success
Mutations of DNA that lead to one base being replaced by another don't have to happen as single, independent events in humans and other eukaryotes, a group of Indiana University Bloomington biologists has learned after surveying ...
