  1. The Structure of the DNA Molecule The finger print that is inside your body!

  2. DNA stands for:D: DeoxyriboseN: NucleicA: Acid DNA is too small to see, but under a microscope it looks like a twisted up ladder!

  3. Every living thing has DNA. That means that you have something in common with a zebra, a tree, a mushroom and a beetle!!!!

  4. DNA

  5. DNA is made up of steps and rails of a ladder. This is a rail This is a step Green can only go with Red Purple can only go with Yellow

  6. Deciphering DNA's structure. • DNA is made up of subunits which scientists called nucleotides. • Each nucleotide is made up of a sugar, a phosphate and a base. • There are 4 different bases in a DNA molecule: • adenine (a purine) • cytosine (a pyrimidine) • guanine (a purine) • thymine (a pyrimidine)

  7. Nucleotides • DNA is made up of subunits which scientists called nucleotides. A nucleotide is a chemical compound that consists of 3 portions: a nitrogenous base, a sugar, and one or more phosphate groups.

  8. 2. Each nucleotide is made up of a sugar, a phosphate and a base. • 3. There are 4 different bases in a DNA molecule: • adenine (a purine) • cytosine (a pyrimidine) • guanine (a purine) • thymine (a pyrimidine)

  9. DNA Molecule • The Impossibility of InformationThe DNA molecule is one of the greatest scientific discoveries of all time. First described by James Watson and Francis Crick in 1953, DNA is the famous storehouse of genetics that establishes each organism's physical characteristics.

  10. DNA is like a fingerprint because everyone’s is a little different! You can tell people apart by their fingerprints……… and their DNA! How would the police look at DNA to figure out who committed a crime?

  11. DNA Molecule Within cells, DNA is organized into structures called chromosomes. These chromosomes are duplicated before cells divide, in a process called DNA replication.
