The complex biological processes by which genetic information is transcribed from DNA to RNA and then translated into proteins, including transcription, translation, and the role of codons and amino acids in determining the final protein product
Summary
Gene expression is a fundamental biological process that allows cells to produce proteins based on the genetic information encoded in DNA. It involves two main stages: transcription, where DNA is converted into messenger RNA (mRNA), and translation, where mRNA is used to assemble amino acids into proteins. Understanding gene expression is crucial for various fields, including genetics, biotechnology, and medicine. The regulation of gene expression ensures that genes are turned on or off as needed, allowing organisms to adapt to their environment and maintain homeostasis. Advances in our understanding of gene expression have led to significant developments in genetic engineering and therapeutic applications, highlighting its importance in modern science and technology.
