Scientists at IOCB Prague are uncovering new details of gene transcription. They have identified a previously unknown molecular mechanism by which the transcription of genetic information from ...

Sidewinder achieves highly accurate assembly of long DNA sequences from scratch, offering a new leap forward for programmable biology ...

Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal ...

DNA can be regarded as an extensive library that contains all genetic information. Cells do not utilize this information simultaneously.

There are a variety of machines, consumables, and safety equipment needed to operate a molecular biology lab. And yes, for the vast majority of labs, purified salmon sperm DNA is one of those ...

Often celebrated as a pioneer of genetics alongside Francis Crick, racist and sexist remarks tarnished his reputation in later years. James Watson was credited as the co-discoverer of the structure of ...

Three biochemical steps of the non-homologous DNA end-joining (NHEJ) process. This figure outlines the key stages of the NHEJ repair mechanism following DNA double-strand breaks. The process can be ...

In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

While the central dogma of molecular biology outlines the linear flow of genetic information from DNA to RNA to proteins (black lines), glycomics introduces a “3rd code of life”—glycans—that operates ...

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 ...

New molecule halts mitochondrial DNA loss before it triggers inflammation. When environmental stress harms DNA, it can set off a cascade of failures linked to heart conditions, neurodegeneration and ...
