INTRO

dolubilization of DNA in water

• observ the formation of a slightly trasparent reddish gelatinous skein (if you have used tomato it should be red)
• with a glass rod try to take the skein to verify its costinstsency
• in a petri dish try to solubilize the DNA in water

STEP 4

MATERIALS

• Tomato
• Extration solution (water and dish cleaner)
• Citric acid (lemon juice)
• Ethyl alcohol 95%
• Becker, test tubes, dropper pipets
• Funnel
• Filter paper
• Blender
• Spinner

gelatinous mass floating in gas during DNA aggregation

precipitation of DNA by insolubility in alcohol

• In a test tube put 2-3 cici of filtered a similar volume of ethyl alcohol make it go along the walls with the dropper to prevant their mixing

STEP 3

opaque coloured liquid containing various chemical components: cell remains (solid) and DNA (in solution)

protein denaturation (chromatine) protein agglutination

membrans dissolution

STEP 1

• Cut two tomatoes into pieces
• Blend the pieces of tomatoes (without skinless) with the extration solution
• In a becker mix the smoothie with the salt solution and the lemon juice

clear-coloured DNA in solution

separation of cellular remains from the liquid

• filter the liquid obtined
• if you want you can centrifuge and take the trasparent liquid in another test tube
