Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment ...

DNA, often called the blueprint of life, is built from four chemical building blocks known as deoxy-nucleoside triphosphates (dNTPs)—dATP, dTTP, dGTP, and dCTP. Cells constantly need these molecules ...

It’s tricky to make an exact copy of yourself. Or at least it is for cells undergoing mitosis, where cells replicate everything inside of them, including their neatly packaged DNA, then split in half.

Iron–sulfur (Fe–S) clusters are evolutionarily conserved cofactors that support an array of DNA replication and repair enzymes. These clusters not only stabilise protein structure but also enable ...

Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist ...

Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell division - a discovery that could lead to new cancer therapies, according ...

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop. Until recently, many fast-changing parts of the human genome remained ...

Scientists say they may be able to design DNA without copying it, opening the door for major advancements in biology and biotech. Specific enzymes can sometimes create DNA that strays from a given ...

“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 ...

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...
