WebNational Center for Biotechnology Information WebApr 8, 2024 · Ribosome profiling (Ribo-seq) is a powerful method to identify proteins involved in translation: ribosomes binding to mRNAs are captured, after which the ribosome-protected RNAs are recovered and subjected to high-throughput sequencing. More ribosomes that bind to RNA indicate a higher likelihood of translation.

WebMar 2, 2024 · The ribosome is one of the largest and most complicated enzymes in cells and is responsible for protein synthesis in all organisms on earth.

The sequence of DNA that encodes the sequence of the amino acids in a protein is transcribed into a messenger RNA chain. Ribosomes bind to messenger RNAs and use their sequences for determining the correct sequence of amino acids to generate a given protein. Amino acids are selected and carried to the ribosome by transfer RNA (tRNA) molecules, which enter the ribosome and bind to the messenger RNA chain via an anti-codon stem loop.
