When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting ...

The human genome consists of 3 billion base pairs, and when a cell divides, it takes about seven hours to complete making a copy of its DNA. That's almost 120,000 base pairs per second. At that ...

Getting DNA into a living cell sounds simple, until you remember the cell’s outer membrane acts like a guarded wall. DNA strands carry a negative charge, and they do not cross that wall easily. So for ...

A newly identified cellular system monitors subtle variations in genetic coding, hinting at a hidden level of control over ...

When a virus infects a bacterial cell, the viral genome is the first component to be fully injected into the cell, making it an ideal immune target. A bacterial enzyme anchored to the membrane ...

Scientists have recently been learning more about the importance of small bits of circular genetic material known as extrachromosomal DNA (ecDNA). These little circles of DNA can hitch a ride with ...

For stem cells to differentiate into the appropriate cell-type, transcription factors (TFs) must be tailored to highly specific expression patterns of lineage-specific genes. Abnormalities in the ...

RIVERSIDE, Calif. -- A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how our bodies sense and respond to stress. The findings ...
