In prokaryotic cells, transcription (DNA to mRNA) and translation (mRNA to protein) are so closely linked that translation usually begins before transcription is complete. In eukaryotic cells, however ...
Every time a cell divides, it must copy roughly three billion letters of DNA with near-perfect fidelity. That copying process, DNA replication, is among the most demanding operations a cell performs, ...
Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins. Scientists ...

Life uses four DNA letters, but scientists made an eight-letter system work
Every known organism writes genetic information with four DNA letters, but laboratory chemistry is not limited to that ...
A detailed picture of what happens when DNA transcription is paused early in the process has been obtained by structural biologists at RIKEN. This could inform the development of new therapies. When ...
Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell division—a discovery that could lead to new cancer therapies, according to ...
A cell protein previously believed only to provide a scaffolding for DNA has also been shown to directly influence DNA transcription into RNA – the first step of the process by which an organism's ...
DNA and RNA methylation, initially thought to operate as distinct pathways, have been shown to interact closely, shifting our understanding of gene regulation. A team of researchers from the ...
Mayo Clinic researchers have identified a protein that acts like a traffic controller for DNA, preventing damage during cell division - a discovery that could lead to new cancer therapies, according ...
We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. In 1957, just four years after Francis Crick and other scientists solved the riddle of ...
A vertical, purple double helix has a bumpy, light-blue shape attached at the bottom and a blue cross made of many strands at the top. One end of the cross is bright pink and has dots around it, and a ...
