Definition
Translation is the biological process in which ribosomes synthesize proteins by decoding messenger RNA (mRNA) sequences into polypeptide chains, utilizing transfer RNA (tRNA) to bring the appropriate amino acids to the growing chain. This process occurs in the cytoplasm and is a crucial step in gene expression following transcription.
Summary
Translation is a vital biological process that converts the genetic information encoded in mRNA into proteins, which are essential for life. It involves several key components, including ribosomes, tRNA, and amino acids, working together in a series of steps: initiation, elongation, and termination. Each step is crucial for ensuring that proteins are synthesized accurately and efficiently. Understanding translation is fundamental to molecular biology and genetics, as it links the genetic code to the functional molecules that carry out cellular processes. Post-translational modifications further enhance the functionality of proteins, making this process a key area of study in biotechnology and medicine.
