As imaging tools continue to get more sophisticated, researchers have been able to actually watch biological processes as they are happening in live cells. Scientists have now visualized loops of DNA ...

Researchers at The University of Texas MD Anderson Cancer Center have shown that DNA inflexibility, or rigidity, inside the ...

The enzyme that drives the intricate process of transcription is known as RNA polymerase. This molecular machine is the ...

RNA mediates essential biological processes in all organisms. These functions include catalysis of crucial biochemical reactions such as peptidyl transfer during translation and transesterification ...

This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...

Researchers discovered that embryos must clear maternal mRNAs to develop properly. When cleanup fails, it causes aberrant transcription and R-loop formation, which blocks DNA replication, damages the ...
