N6-methyladenosine

N6-methyladenosine (m6A) is a chemical modification found on RNA molecules, specifically on adenosine bases. It acts like a molecular marker that influences how RNA functions within cells, affecting processes such as gene expression, RNA stability, and protein production. Think of it as a tag that helps the cell decide how to handle the RNA, shaping biological activities like development and responses to environment. m6A is one of the most common and studied modifications on messenger RNA (mRNA), playing a crucial role in regulating cellular functions and health.
