DNA replication and repair mechanisms constitute the foundation of genomic integrity, ensuring that genetic information is faithfully duplicated and maintained across cell generations. Replication ...

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 ...

Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to some ...

In honour of National DNA day and the 70th anniversary of the discovery of the structure of DNA, biology teachers and students at Pennsbury High School in Fairless Hills, Pennsylvania, USA, wanted to ...

Seventy years ago, two male scientists, Francis Crick and James Watson, proclaimed they had discovered the secret of life: the structure of DNA. Since then, history has acknowledged how Rosalind ...
