PPT--Bio Lab - DNA Structure & DNA Replication

What is DNA DNA is a Nucleic Acid in the nucleus Polymer of Nucleotides Each nucleotide consists of Deoxy ribose 5carbon sugar Phosphate group a nitrogencontaining base Four bases. 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. . DNA or Protein?. Walter Sutton discovered . chromosomes . were made of . DNA and Protein. However, scientists were . NOT . sure which one (protein or DNA) was . the actual genetic material of the cell. Dr. Kevin Ahern. Structure. Structure. Structure. One Strand of DNA.
