Nucleotides are made up of phosphate, sugar, and nitrogen bases. The base pair rules are A=T and G= C. Nitrogen Bases are connected by special chemical bonds called hydrogen bonds. DNA looks like watery slime and gooey. ]]> 2022-03-16 16:12:52 UTC https://padlet.com/kevint729141/qx8v474tqnu7rd9s/wish/2098378693 SECTION 2 kevint729141 https://padlet.com/kevint729141/qx8v474tqnu7rd9s/wish/2098382007 2022-03-16 16:14:36 UTC https://padlet.com/kevint729141/qx8v474tqnu7rd9s/wish/2098382007 STRAWBERRY DNA EXTRACTION LAB SECTION 3 kevint729141 https://padlet.com/kevint729141/qx8v474tqnu7rd9s/wish/2098384024 2022-03-16 16:15:44 UTC https://padlet.com/kevint729141/qx8v474tqnu7rd9s/wish/2098384024 STRAWBERRY DNA EXTRACTION LAB SECTION 4 kevint729141 https://padlet.com/kevint729141/qx8v474tqnu7rd9s/wish/2098392503 heavy duty ziploc bag

Afterwards, I mushed the strawberry with salty/soapy solution to break up proteins & dissolve cell membranes. Next, I filtered the strawberry slurry through cheesecloth to break up proteins & dissolve cell membranes. Lastly, I added an addition of ethanol to the filtered extract so that the DNA could precipitate from the solution.

What I learned about DNA is that it is not invisible to the naked eye but if gathered together it becomes visible. What I would do differently in this experiment if given another chance is breaking down the strawberry a bit more. After extracting the DNA I would observe the DNA and throw away stuff that isn't needed anymore. Two traits that are expressed in a strawberry are its size and color
