RNA is a tiny molecule that delivers genetic messages within cells. It works with proteins to control genes, adapt to the environment, and carry out important tasks. Different types of RNA, like mRNA, tRNA, and rRNA, help build proteins and keep cells functioning properly. Sometimes, RNA can have problems, causing genetic disorders or viral infections. But overall, RNA acts like a conductor, making sure genes are used at the right times, creating a harmonious symphony of life inside our cells.
