The Marvel of Molecular Biology The Central Dogma of Life, a fundamental concept in molecular biology, describes the flow of genetic information within a biological system. It was first proposed by Francis Crick in 1958 and further expanded upon in 1970. The Central Dogma involves three key processes: DNA replication, transcription, and translation DNA Replication DNA replication is the process by which a cell duplicates its DNA before cell division, ensuring that each new cell receives an exact copy of the genetic instructions. The replication process begins at specific locations on the DNA molecule called origins of replication, where the double helix unwinds to expose the template strands. Each strand of the DNA molecule serves as a template for the synthesis of a new complementary strand, following the base pairing rules (A pairs with T, and G pairs with C). The result is two identical DNA molecules, each composed of one original strand and one newly synthesized strand . Tra
