DNA

DNA

DNA stand for DeoxyriboNucleic Acid
1. Contains all the instrutions to put organisms together and make it work
2. DNA found in the Nucleus of animals and plants
3. Inside long molecules called chrosomes
A gene codes for a specific protein
1. A gene is a section of DNA
  1. Contains the instrutions to make specific proteins
2. Cells make proteins by stringing amino acids together in a particular order
3. Only 20 amino acids are used

6. That in turn determines what type of cell it is

1. Almost everyone's DNA is unique
  1. Apart from identical twins and clones
2. DNA fingerprinting (or genetic fingerprinting)
  1. A way of cutting up a person's DNA into small sections and then separating them
    1. everyone's fingerprint has a unique pattern
      1. Apart from Identical twins and clones
    2. You can tell people apart by DNA fingerprinting of their DNA
3. DNA Fingerprinting is used in:
  1. Forensic Science
    1. DNA from:
      1. hair
      2. Skin flakes
      3. blood ect..
  2. Paternity testing
