New research shows that we regularly transfer traces of our genital microbiomes to sexual partners—a discovery that could ...

Earlier studies of ribosomal RNA (rRNA) sequences have concluded that the oldest ... France, report a re-analysis of bacterial phylogeny that challenges this dogma (Nature 2002, 417:244). It is widely ...

Bacteria modify their ribosomes when exposed ... These molecular structures create proteins and are themselves made of proteins and ribosomal RNA. Ribosomal RNA is often modified with chemical ...

For instance, a review focused on the small ribosomal subunit biogenesis in bacteria identified several key proteins, such as GTPases and RNA helicases, that facilitate the proper folding and ...

Wikimedia Commons Ribosomal DNA (rDNA) codes for the RNA that makes up a major component of ribosomes, the site of protein synthesis. Ribosomal RNA (rRNA) comprises 80% of the RNA found in a typical ...

For instance, bacteria contain a single type of RNA ... RNA pol I transcribes ribosomal RNAs (rRNAs), RNA pol II transcribes RNAs that will become messenger RNAs (mRNAs) and also small regulatory ...

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

"They then assemble in a coordinated fashion on the appropriate ribosomal RNA moiety to form mitoribosomes in the organelle with the help of special factors." Like ribosomes in bacteria or the ...

This image highlights two alternatives for the ribosome to be recruited to an mRNA that is still being synthesized by RNA ... dominant in bacteria, RNAP (green) can interact with ribosomal protein ...

Ribosomal translation is the process by which cells synthesize proteins based on the genetic instructions encoded in messenger RNA. It is essential for life, yet it is an incredibly complex ...
