Epigenetic clocks that quantify rates of aging from DNA methylation patterns across the genome have emerged as a potential biomarker for risk of age-related diseases, like Alzheimer’s disease (AD), ...

Researchers have uncovered which genes on the Y chromosome ... In a significant proportion of cases, genetic factors, particularly those involving the Y chromosome, are the cause.

This inactivation is through epigenetic mechanisms — modifications to the genome that do not alter the DNA sequence but regulate gene expression ... Sex-chromosome-related genetic differences ...

“Given the fact that the X chromosome is enriched for brain-related genes, it became very important for us to know what roles it might be playing in brain aging,” said Samira Abdulai ...

Thomas Hunt Morgan (shown) discovers a white-eyed mutant in his laboratory fruit flies. His continuing work would confirm that genes, the units of heredity, are located on chromosomes.

The genomic DNA ... Gene flow between populations likely contributes to higher genetic variance within populations. Four SNPs significantly associated with days to 50% flowering, days to 90% maturity, ...

To turn genes off and on, cells use Structural Maintenance of Chromosomes (SMC) motors that act like switches to connect different parts of DNA," first author Roman Barth explains. "However ...
