the structure of DNA they wanted to use the information to help them identify how DNA is replicated. Three different theories of replication were proposed by Watson and Crick. The semi-conservative model‚ where the DNA strand splits into two halves‚ which will then create a new DNA strand consisting of the old original half and a new half. The conservative model where the whole of the original DNA strand acts as a template and is replicated to make a completely new strand of DNA. The dispersive model

Biology Notes 1.02 Sometimes a practice or belief claims to be science but does not follow the scientific method or cannot be proven reliable through experimentation. These practices are examples of pseudoscience‚ which literally means "fake science." Charms‚ astrology = stars‚ and phrenology= reading the bump on skull 1.03 * In the mid 1600s in the Netherlands‚ the scientist Antonie van Leeuwenhoek developed the first known microscope using a single magnifying lens. He was the first person
