RNA News

RNA, or ribonucleic acid, is a crucial molecule in cellular biology, playing several vital roles in the processes of translating genetic information into proteins. Structurally similar to DNA, RNA is typically single-stranded and contains a ribose sugar, with uracil (U) replacing thymine (T) as one of the nitrogenous bases. RNA serves various functions within the cell, primarily involving the coding, decoding, regulation, and expression of genes. The three main types of RNA are messenger RNA (mRNA), which carries the genetic blueprint from DNA to the cell’s protein-making sites; ribosomal RNA (rRNA), which forms part of the ribosome and orchestrates protein synthesis; and transfer RNA (tRNA), which helps assemble protein by bringing the appropriate amino acids in line with the mRNA sequence on the ribosome. Additionally, RNA plays a role in gene regulation and has been implicated in various cellular mechanisms including those involved in diseases and the body’s response to infections. The study of RNA has also led to significant biotechnological advances, such as RNA interference and mRNA-based vaccines.
