DNA

• DNA is a double-stranded molecule that forms a helical structure.
• suitable plant tissue DNA may be isolated from inion
• a DNA molecule shape is double helix
• coding DNA has a template for the production of protein
• Non-coding DNA does not have a template for the production of protein
• steps in isolating DNA from plant tissue

  1. Chopping or making a paste for the plant tissue 2.Adding a detergent to the chopped tissue

  3. Adding salt to the chopped tissue

  4. Filtering mix

  5. Adding ethanol
• 1. chopping or making a paste increases surface area for the next steps
• 2. adding detergent Breaks nuclear and cell membrane to release the DNA
• 3. adding salt Causes DNA molecules to clump together
• 4. Filtering the mixture separates the solution containing DNA and protein from the rest of the cell debris
• 5.adding ethanol Makes DNA visible
• isolated DNA appears white and thread like material
• safety precautions taken wear safety gloves
