A new study looks at the process of DNA methylation, in which chemical tags known as methyl groups turn genes on and off and ...

A routine experiment with a new single-cell DNA sequencing method turned into a surprising scientific twist when researchers ...

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

DNA repair mechanism: HELQ helicase remodels stalled replication forks into stable structures, preventing harmful mutations under replication stress. Advanced imaging tool: RF-SIRF maps reversed forks ...

Ancient DNA power: Harvard-led research on nearly 16,000 ancient genomes shows intensified natural selection over the past 10,000 years, reshaping hundreds of human genes. Rare variant advances: New ...

If parent cells and their daughter cells are to share a stable identity, parent cells must divide—and replicate their DNA—while ensuring that their histones are distributed properly to their daughter ...

Inhibiting RNase H2 increases DNA damage and activates immune responses in triple-negative breast cancer, suggesting a ...
