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. • • #snRNA: Small nuclear RNA (snRNA) is involved in the processing of pre-messenger RNA (pre-mRNA) molecules within the nucleus. • Working together with proteins, snRNA forms small nuclear ribonucleoprotein particles (snRNPs) that recognize specific sequences in pre-mRNA, promoting the removal of non-coding regions (introns) and the joining of coding regions (exons) through a process called splicing. • • #snoRNA: Small nucleolar RNA (snoRNA) is a diverse group of RNAs found in the nucleolus of eukaryotic cells. • They primarily function in the modification and processing of other RNA molecules, particularly rRNA and tRNA. By guiding enzymes to specific nucleotide sites, snoRNAs play a crucial role in ensuring their proper functionality. • #miRNA: MicroRNA (miRNA) is a class of small non-coding RNA molecules that regulate gene expression by targeting messenger RNA (mRNA) molecules. • Through base-pairing with specific sequences in the mRNA, miRNAs can inhibit translation or promote degradation of the mRNA, thereby fine-tuning gene expression. • • #siRNA: Short interfering RNA (siRNA) is a double-stranded RNA molecule that can trigger gene silencing through a process called RNA interference . • By targeting complementary mRNA sequences, siRNAs facilitate the degradation of the targeted mRNA molecules, preventing their translation into proteins. • #lncRNA: Long non-coding RNA (lncRNA) is a diverse group of RNA molecules that do not encode proteins but play critical roles in gene regulation and cellular processes. • LncRNAs have emerged as important regulators in development, cancer, and other biological process • #types_of_RNA_produce_cell
