Only recently has the ribosome—one of the oldest molecular machines in evolutionary terms—been recognized as an active ...

"95% of human RNA is ribosomal RNA. They are very prevalent in our cells," adds Dr. Novoa. The researchers looked for all types of chemical modifications across human and mouse rRNA from many ...

Furthermore, many other varieties of RNA have been found to have complex regulatory roles in cells. Thus ... the structure where rRNA processing and ribosomal assembly take place.

Proteins that trigger cell senescence occupy much of the literature on aging, but a small RNA moves into the limelight ... “Almost all of the factors that we know that are involved in building ...

The rRNA structures also provide binding sites for ribosomal proteins, which help stabilize the overall structure of the ... This discovery led to the concept of the ribosome as a ribozyme, an RNA ...

In the microscopic world of bacteria, gene transfer is a powerful mechanism that can alter cellular function, drive antibiotic resistance and even shape entire ecosystems.

Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U). RNA is often compared ...

Ribosomal RNA (rRNA) is a component of the ribosomes ... These RNA molecules can interact with mRNA, influencing its stability, translation, or degradation, thus fine-tuning protein production in the ...

to "barcode" ribosomal RNA (rRNA) inside living cells. By writing genetic information directly into the 16S rRNA -- a molecule universally found in bacteria -- the researchers could track which ...
