RNA (Ribonucleic Acid) is a type of nucleic acid that plays a crucial role in various biological processes within cells. It is responsible for transmitting genetic information from DNA to proteins, as well as regulating gene expression and carrying out various cellular functions. RNA can exist in multiple forms, such as messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA), each serving specific roles within the cell. Research in the field of RNA focuses on understanding its structure, function, and regulation, as well as its potential applications in medicine, biotechnology, and genetic engineering. Recent advancements in RNA research have led to the development of RNA-based therapeutics, such as RNA interference (RNAi) and antisense oligonucleotides, which have shown promising results in the treatment of various diseases.
