Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins.

At this point, translation must be terminated, and the nascent protein must be released from the mRNA and ribosome. Termination of Translation There are three termination codons that are employed ...

During translation, multiple ribosomes travel along the nucleic acid chain to build polypeptides that become functional proteins. Occasionally, these molecular decoders pause on the mRNA, either ...

This new technique enables researchers to monitor an individual ribosome over time during mRNA translation. Using their technique, the team has already gained new insights into how ribosomes function.

However, the infection did modify the underlying molecular structure of the ribosome, leading to increased poxvirus protein translation. Genetic knockout screens coupled with metabolic assays ...

We showed that non-AUG translation is strikingly resistant to multiple protein synthesis inhibitors, including cycloheximide. We find that these inhibitors slow elongating ribosomes, thereby inducing ...

A new review article highlights the transformative role of circular RNA (circRNA) in cancer, revealing its potential as both a key player in tumor biology and a promising avenue for future therapies.

The catalytic center of the ribosome, known as the peptidyl transferase center (PTC), is composed entirely of rRNA. The PTC is highly conserved across all domains of life, highlighting the fundamental ...

During protein synthesis, the genetic information stored in DNA is first transcribed into mRNA. The mRNA then travels to the ribosome, where translation occurs. Here's how anticodons facilitate the ...

We call this a complementary copy. The newly formed strand of mRNA is now ready to leave the nucleus and travel to the ribosome. After translation, the polypeptide is finally folded into the ...
