DNA, which has a double-helix structure, can have many genetic mutations and variations. Credit: NIH When cells in the human body divide, they must first make accurate copies of their DNA. The DNA ...

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 ...

The process begins by unzipping DNA's ladder-like structure, resulting in two strands called the leading and lagging strands. A molecular construction crew then assembles the missing halves of the ...

A research team has analyzed the three-dimensional structure of a protein that suppresses the development of colorectal polyposis, MUTYH, at the atomic level and clarified the repair mechanism for DNA ...

Maize serves as a vital model species for advancing our understanding of plant biology, yet many mysteries remain about the ...

DNA replication is a complex process with many moving parts. In baker's yeast, the molecular complex Ctf18-RFC keeps parts of the replication machinery from falling off the DNA strand. Human cells use ...

New research shows hydroxyurea reshapes DNA replication in cancer cells, revealing stress responses that may help design ...

Ongoing research aims to confirm the mechanism by which ICP4 fluidizes the nucleus, which could indicate specific targets to counter viral replication.
