Thus, RNA molecules play numerous roles in both normal ... the nucleolus is the structure where rRNA processing and ribosomal assembly take place. Molecules called small nucleolar RNAs (snoRNAs ...

messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). Although some RNA molecules are passive copies of DNA, many play crucial, active roles in the cell. For example, some RNA ...

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 ...

The tRNA binds to its corresponding amino acid and transports it to the ribosome, where it is incorporated into the growing polypeptide chain. Ribosomal RNA (rRNA) is a component of the ribosomes, the ...

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. Now an interdisciplinary ...

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

Ribosomes are made of proteins and a special type of RNA molecule called ribosomal RNA (rRNA). rRNA molecules are the target of chemical modifications, affecting the ribosome's function.
