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

DNA is a biological molecule that contains the instructions an organism needs to function, develop, and reproduce. It is present in all forms of life on earth and contains each organism’s genetic code ...

Deoxyribonucleic acid (DNA) replication is fundamental to life, yet the precise mechanics of how helicases unwind the genome for replication remain unclear. A recent study published in Nature used ...

In our bodies, there are trillions of cells. From white blood cells to skin cells, each type has its own specific function which helps us perform tasks and survive. But what makes up these cells and ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

What do a human, a rose, and a bacterium have in common? Each of these things — along with every other organism on Earth — contains the molecular instructions for life, called deoxyribonucleic acid or ...

Embryonic cells need to divide, fast. But mess with their chromatin, and they’ll stall. The moment a sperm and egg fuse, they become something special: a totipotent zygote cell, fast-dividing and able ...

MINNEAPOLIS / ST. PAUL--In order to divide, cells must first replicate their chromosomes. Cells use an array of proteins to accomplish the job, including a large enzyme complex that synthesizes new ...
