Non-coding RNA

Non-coding RNA (ncRNA) refers to a group of RNA molecules that do not translate into proteins but play crucial roles in regulating gene expression and cellular functions. Unlike messenger RNA (mRNA), which serves as a blueprint for protein production, ncRNAs influence processes such as gene silencing, RNA splicing, and chromosome structure. Examples include microRNAs, which help control the levels of proteins in cells, and long non-coding RNAs, which can regulate gene activity. Understanding ncRNA is vital for advancing knowledge in fields like genetics, molecular biology, and medicine, as they are involved in various biological processes and diseases.
