Brief Introduction to Types of ‘RNA’ (TS. Đinh Phong Sơn)
mRNA: Messenger RNA (mRNA) is a crucial molecule that carries genetic information from the DNA to the ribosomes, where it serves as a template for protein synthesis. This single-stranded molecule plays a pivotal role in the process of transcription and translation, making it a key player in gene expression and protein production.
tRNA: Transfer RNA (tRNA) is a small RNA molecule that acts as an interpreter between mRNA and amino acids during protein synthesis. It carries specific amino acids to the ribosomes, where they are assembled into a polypeptide chain according to th instructions encoded in the mRNA. With its unique cloverleaf-like structure and anticodon region, tRNA ensures the accurate translation of genetic information into functional proteins.
rRNA: Ribosomal RNA (rRNA) is a fundamental component of ribosomes, the cellular machinery responsible for protein synthesis. It forms the core of the ribosome and provides structural support while facilitating the catalytic activity of the ribosome during translation. Multiple types of rRNA molecules work together to ensure the accurate assembly of proteins, making rRNA an essential participant in the intricate process of protein synthesis.
