👉 In biology and genetics, a "saprogenous" gene is an enzyme that plays a crucial role in the process of DNA replication. These enzymes are responsible for synthesizing new DNA strands from old ones, ensuring the integrity of the genetic material during cell division. The term comes from the Sapogenus genus of fungi, which is known for its ability to synthesize and regenerate saprophytic bodies from dead host cells or tissues. This process involves the production of a complex mixture of enzymes that are
