Fly Researchers at Duke University Find Another Layer to the Code of Life

[ad_1] New research has revealed that the brain and testes appear to be extremely adaptable to the use of many different kinds of genetic code to produce a given protein. Rare pieces of genetic code may serve as another way to control cellular machinery. A new investigation into the way different tissues read information from […]

Scientists Find That DNA Mutations Are More Common Than Previously Thought

[ad_1] Researchers at EMBL Heidelberg found that inversions in the human genome are more common than previously thought, which impacts our understanding of certain genetic diseases. Our DNA serves as a blueprint for the cellular machinery that allows cells, organs, and even whole organisms to work. However, mutations in our DNA can cause genetic illnesses. […]

How Do Genomes Evolve Between Species? The Key Role of 3D Structure in Sperm Cells

[ad_1] New research shows that sperm production is critical to how regions of the genome are re-organized within and between chromosomes during evolution. In particular, inherited chromosomal rearrangements are associated with physical and biochemical processes that are specific to the final stages of sperm production, after the meiotic cell divisions have completed. A study led […]

Squid and Octopus Genomes Reveal How Cephalopods’ Unique Traits Evolved

[ad_1] The Atlantic longfin inshore squid, Doryteuthis pealeii, has been studied for nearly a century by scientists as a model system for neuroscience investigations. Credit: Elaine Bearer Squid, octopus, and cuttlefish – even to scientists who study them – are wonderfully weird creatures. Known as the soft-bodied or coleoid cephalopods, they have the largest nervous […]

Biochemists Identify How Genome Organization Influences Cell Fate

[ad_1] Cell nucleus illustration. University of California Riverside-led study identifies how blood stem cells maintain their fate. Understanding the molecular mechanisms that specify and maintain the identities of the human body’s more than 200 cell types is perhaps one of the most fundamental problems in molecular and cellular biology, with major implications for human disease […]

Structures Considered Key to Gene Expression Are Surprisingly Dynamic and Short-Lived

[ad_1] MIT researchers have discovered that chromatin spends most of its time in a partially looped state (middle). Fully formed loops (right) occur only three to six percent of the time, they found. Credit: Courtesy of the researchers, edited by MIT News MIT research finds genome loops don’t last long in cells; theories of how […]

Scientists Have Finally Sequenced the Complete Human Genome – And Revealed New Genetic Secrets

[ad_1] Sequencing the last 8% of the human genome has taken 20 years and the invention of new techniques for reading long sequences of the genetic code, which consists of the nucleotides C, T, G and A. The entire genome consists of more than 3 billion nucleotides. Credit: Ernesto del Aguila III, NHGRI Repetitive DNA […]

Hidden Regions Revealed in First Complete Sequence of a Human Genome

[ad_1] Parts of the human genome now available to study for the first time are important for understanding genetic diseases, human diversity, and evolution. The first truly complete sequence of a human genome, covering each chromosome from end to end with no gaps and unprecedented accuracy, is now accessible through the UCSC Genome Browser and […]
