MicroRNAs regulate protein production through base pairing with complementary mRNA codes, acting like a lock and key. This binding leads to inhibition of protein translation from mRNA as well as degradation of the mRNA itself. The document outlines preparing a search strategy to answer the research question: how do microRNAs interact with RNA to inhibit protein translation? It identifies the main concepts of microRNAs and translation, and their synonyms, to create a search statement combining these terms.
