Japan-based biochemist Ali Malay has long questioned traditional theories about how spiders make their silk. “The prevailing hypotheses seemed like magic, because, according to it, you suddenly have ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication ...

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular ageing, cancer, ...

Multicellular organisms (animals, plants, humans) all have the ability to methylate the cytosine base in their DNA. This process, a type of epigenetic modification, plays an important role in ...

A Nobel laureate, he identified an enzyme that cuts DNA, laying the groundwork for milestones in scientific research and ...

The universal features that define genomic regions acting as replication origins remain unclear. In this study, we mapped a set of origins in Trypanosoma brucei using stranded short nascent strand ...

When DNA breaks, cells must repair it accurately to prevent harmful mutations. Researchers have discovered that during a key repair process called homologous recombination, the cell uses loops in its ...

The diversity of unicellular eukaryotes covered in the study, with their nucleus (blue) and microtubule cytoskeleton (magenta) stained. These organisms are so distantly related to each other as they ...

Researchers created a highly efficient gene-editing method that fixes multiple DNA mutations in a single step. The breakthrough could revolutionize genetic medicine by making treatments for complex ...
