Researchers found a new mechanism for gene evolution, with antifreeze fish using non-coding DNA to create a functional protein. This discovery challenges conventional thinking on gene origins and may provide insights into the emergence of new functions in living organisms.
Scientists have identified human enhancers able to control expression consistent with the zebrafish ret gene, shedding light on Hirschsprung disease and multiple endocrine neoplasia. The new system uses zebrafish to test mammalian DNA and is a significant advance over current methods.
A recent UCSD study shows that non-coding regions of DNA, often referred to as 'junk' DNA, are essential for maintaining an organism's genetic integrity and play a crucial role in evolutionary survival. These findings suggest that these regions are not functionally inactive but rather provide resistance to new mutations.
Researchers found that longer junk DNA variations affected gene expression patterns in the brain of male prairie voles, leading to increased social behavior and parental care. The study's findings have implications for understanding human social diversity and personality traits.
Researchers discovered over 2,200 new human-specific Alu DNA repeats not found in chimpanzees, suggesting an explosive expansion of genetic code. This finding contradicts the idea of natural selection and highlights a chemical process driving human evolution.
Study reveals that heterochromatin forms despite lack of key RNA silencing components, indicating multiple pathways for chromosome regulation. Understanding these mechanisms is crucial for developing gene therapy to conquer chromosomal abnormalities and birth defects.
Researchers found a new regulatory gene, SRG1, which blocks the expression of adjacent genes by physically preventing transcription factors from binding. This discovery provides evidence that junk DNA may have hidden functions and could be a common mechanism for regulating gene expression.
Researchers have discovered that LINE-1 elements, which make up 17% of human DNA, can cause broad-spectrum mutations by deleting genetic material. In cultured human cancer cells, these elements can delete large segments of DNA, including regions as big as the BRCA1 gene.
A new research tool developed at USC promises to speed dramatically the hunt for disease-causing genes by reconstructing gene layouts. The ExonPCR technique uses a series of 'yes' or 'no' answers, similar to the parlor game '20 Questions,' to narrow down possibilities and solve the riddle.
