WebRibosome profiling is based on the discovery that the mRNA within a ribosome can be isolated through the use of nucleases that degrade unprotected mRNA regions. This technique analyzes the regions of mRNAs being converted to protein, as well as the levels of translation of each region to provide insight into global gene expression. WebRibosomes synthesize protein in a process called translation where they “read” strands of mRNA and bring the right amino acids together to build a long polypeptide chain that that will ...
