The enzyme RNA polymerase (RNAP) carries out transcription, copying DNA into RNA. It's the first step in gene expression, and ...

Researchers at The University of Texas MD Anderson Cancer Center have developed a new imaging method, known as RF-SIRF, that ...

Before a cell divides into two, it must first copy its DNA, so that each new cell receives a complete set. Occasionally, what ...

Real image of DNA molecules being copied in human cells, visualized by immunofluorescence microscopy. The yellow arrows mark where replication begins, and the white arrows indicate the direction in ...

From the elegant spirals of the double helix to the bustling activity at replication forks, your DNA is constantly at work — and under threat. Scientists are uncovering how it copies itself with ...

Johns Hopkins Kimmel Cancer Center scientists report data from a new study providing evidence that random, unpredictable DNA copying "mistakes" account for nearly two-thirds of the mutations that ...

A new study has uncovered a hidden step that helps the deadliest malaria parasite survive and multiply inside the human body. Researchers studying Plasmodium falciparum found that the parasite relies ...

During DNA replication, the unwinding of strands leaves a single strand vulnerable. How does the cell protect these strands from damage? How would you identify the protein that serves as a connector ...

Researchers have found that the way DNA is packaged in cells can directly impact how fast DNA itself is copied during cell division. They discovered that DNA packaging sends signals through an unusual ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

In a new study, scientists analyzed one such strategy used by the bacterium Escherichia coli. One of the enzymes in the ...
