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 replication is one of life’s most precise and essential processes, ensuring genetic information is faithfully passed from cell to cell and generation to generation. This remarkable molecular ...

Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of years later. Scientists have now discovered that a molecular system once ...

For decades, scientists believed a fertilized egg’s DNA began as a shapeless mass, only organizing itself once the embryo switched on its genes. But new research reveals that the genome is already ...

DNA is often called the blueprint of life, but what does that really mean? Elizabeth Worthey, Ph.D., associate professor, Department of Genetics in the Heersink School of Medicine, explains everything ...

Researchers at The University of Texas MD Anderson Cancer Center have developed a new imaging method, known as RF-SIRF, that quantitatively detects and maps reversed DNA replication forks with ...

The herpesvirus can manipulate our DNA with far more precision than previously thought. The virus condenses and changes the shape of our genetic material to hijack the host genes needed for ...

Replication origins in Trypanosoma brucei integrate multiple features previously described individually in opisthokonts, revealing a unified structural topology built from strand-specific nucleotide ...

“The laws of inheritance are quite unknown,” Charles Darwin acknowledged in 1859. The discovery of DNA’s shape altered how we conceived of life itself. The X-ray crystallography by Rosalind Franklin ...

Researchers at The University of Texas MD Anderson Cancer Center have identified a key enzyme—RNase H2—that helps triple-negative breast cancer (TNBC) cells survive high levels of DNA replication ...
