Molecular biology is a field that delves into the molecular underpinnings of biological activity in cells, including DNA replication, transcription, and translation. It encompasses the central dogma, which outlines the flow of genetic information, and the genetic code's role in protein synthesis. Advances in genomics and proteomics, powered by technological breakthroughs like high-throughput sequencing, have transformed our understanding of gene and protein functions, leading to novel applications in various industries.
