From the first unzip of the double helix to the final joining of DNA fragments, replication is a carefully coordinated process. Understanding it helps explain how life preserves its genetic code with ...

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 ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

Every person starts as just one fertilized egg. By adulthood, that single cell has turned into roughly 37 trillion cells, many of which keep dividing to create the same amount of fresh human cells ...

In a twist on the question, 'Which came first, the chicken or the egg?', scientists have long faced a similar question about how human adenovirus replicates: 'Which comes first, assembly of the viral ...

Researchers have identified an alternate method to study changes during the DNA replication process in lab settings using genetically modified yeast. The new approach offers a clearer window than ...

As cells divide, they must copy all of their chromosomes once and only once, or chaos would ensue. How do they do it? By Amber Dance/Knowable Magazine Published Jul 7, 2023 6:00 PM EDT This article ...

This illustration shows proteins and DNA in the process of DNA repair. RecA proteins (gold) cradle a single-stranded DNA (brown) that searches for homology with a DNA template (purple). The template ...

Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...
