U1 RNA

U1 RNA is a small RNA molecule that plays a crucial role in the cell’s process of editing and shaping messenger RNA (mRNA), which carries genetic instructions from DNA to make proteins. It is part of a larger complex called the spliceosome, which helps remove non-essential regions from pre-mRNA, ensuring accurate protein production. U1 RNA specifically recognizes and binds to specific signals on the pre-mRNA, guiding the spliceosome to the correct sites. This process is essential for producing functional proteins and maintaining healthy cell function.
