The landmark ideas of Watson and Crick relied heavily on the work of other scientists. What did the duo actually discover? Many people believe that American biologist James Watson and English ...

Replication Protein A (RPA) is the principal single-stranded DNA (ssDNA)-binding complex in eukaryotic cells, orchestrating fundamental processes of DNA replication, repair and recombination. As a ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...
