Ribosomal RNA (rRNA) is a type of molecule and a key building block of the ribosome, the cell's protein-making machinery. rRNA accounts for much of the RNA in a cell, and it's crucial for life. It's ...

The enzyme that makes RNA from a DNA template is altered to slow the production of ribosomal RNA (rRNA), the most abundant type of RNA within cells, when resources are scarce and the bacteria ...

Hyperthermophilic archaea are true survival experts. They thrive in boiling hot springs and deep-sea vents—environments ...

Two key sequencing techniques are no longer at odds, thanks to an international effort led by scientists at University of California (UC) San Diego. The researchers have developed a reference database ...

Hypoxia -- where a tissue is deprived of an adequate supply of oxygen -- is a feature inside solid cancer tumors that renders them highly invasive and resistant to treatment. A study of how cells ...

"A lot of biochemical and genetic data had been generated," says Venki Ramakrishnan, group leader, structural studies division, Medical Research Council Laboratory of Molecular Biology, UK. "But it ...

Now, a new study from Dr. Rigoutsos' lab shows that the rRNA sequences of several organisms contain special patterns that are unique to each organism and shared primarily with genes of the nervous ...
