Transcription / RNA Synthesis
Transcription, a fundamental process in molecular biology, is the synthesis of RNA from a DNA template. This intricate mechanism plays a pivotal role in gene expression, facilitating the transfer of genetic information from the nucleus to the cytoplasm where it directs protein synthesis. Through a series of precise biochemical steps, including initiation, elongation, and termination, transcription ensures accurate replication of the genetic code. Understanding the intricacies of transcription is crucial for unraveling the complexities of cellular function and disease processes, making it a focal point of research in fields ranging from genetics to medicine.
Questions
