RNA represents a type of biological molecule known as nucleic acid. It plays several critical roles in the cell, particularly in protein synthesis. RNA is transcribed from DNA and acts as a template for the synthesis of proteins in a process called translation. There are various forms of RNA, including messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA), each serving distinct functions within the cell. Understanding RNA's structure and function is essential in genetics, molecular biology, and biomedicine.
