PPT-DNA Structure, Function, & Replication

Biology Unit 6 Part 2 What is DNA DNA Deoxyribonucleic Acid Contains information needed for the cells growth and other activities Determines the inherited characteristics of an organism. DNA Structure. The discovery of the structure. Francis Crick and James Watson. The deoxyribonucleic acid (DNA) molecule is the genetic blueprint for each cell and ultimately the blueprint that determines every characteristic of a living organism. The DNA molecule was discovered in 1951 by Francis Crick, James Watson, and Maurice Wilkins using X-ray diffraction. . 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. Twelfth Edition. Chapter 9. DNA Structure and .
