steps
03
05
01
add alchohl by sliding it along the test tube's walls
with the funnel filter the fluid in a tube
blend the fruit with water in order to make a fluid
02
04
06
in the becher mix the fluid with lemon juice and salt
with the pipettes bring the gelatinous solution between two phases
split the solution in different tubes
observations
03
01
we added alchohl in order to precipitate the dna cause of the solubility of the substances
we added lemon juice and salt in order to denature and agglutinate proteins
04
02
the dna will be between the surnatant phase an the pellet
the fluid will be divided in supernatant solution (alcohol) and the pellet (fruit)
