Replication is the process of making an exact copy of something. In scientific research, it refers to repeating an experiment to see if the same results can be achieved. This is important for verifying findings and ensuring that they are reliable and not just due to chance. In the context of biology, replication often refers to the duplication of DNA during cell division. This process ensures that each new cell receives an identical set of genetic information. Accurate replication is crucial for maintaining the integrity of an organism's genetic material across generations.
