PPT-DNA Replication When/why do cells need to

replicate copy DNA Growth Reproduction Repair Where do we start Replication origin a specific sequence of DNA or region on a chromosome at which DNA synthesis or replication begins. TRILLIONS!. How many of those cells contain your DNA?. All of them! All of your cells contain a . complete. copy of your genome (DNA)!. Your life started as just 1 cell. How do we come from 1 cell & end up as trillions?. Katie Thompson. History of Nucleus. In 1911 Earnest . R. utherford discovered a nucleus in an atom. Experimented by shooting X-rays that contained positively charged alpha particles at gold foil. The X-rays were shot through the middle of an atom and bounced back demonstrating a densely populated area of other positive particles. BIO…. LIFE….. THINK ABOUT THIS: .

DNA . replication occurs in all living organisms acting as the most essential part for biological inheritance. This is essential for cell division during growth and repair of damaged tissues, while it also ensures that each of the new cells receives its own copy of the DNA. Mitosis, Protein . Synthesis.
