Do strawberries or bananas have more DNA?

Do strawberries or bananas have more DNA?

Do strawberries or bananas have more DNA?

Strawberries are an exceptional fruit to use for this DNA extraction lesson because they yield more DNA than any other fruit (i.e. banana, kiwi, etc.). Strawberries are octoploid, meaning that they have eight copies of each type of chromosome.

Are strawberries The only item that works for a DNA extraction Why or why not?

While other fruits are soft and just as easy to pulverize, strawberries are the perfect choice for a DNA extraction lab for two very good reasons: (1) they yield way more DNA than other fruits, and (2) they are octoploid, meaning that they have eight copies of each type of DNA chromosome.

Which has more DNA strawberry or kiwi?

I think the strawberry will extract more DNA because I know that strawberries are octoploid, meaning that they have 8 copies of each type of DNA chromosome. That means they have a lot of DNA per cell. A kiwi is only hexaploid, which means that they have 6 copies of each type of DNA chromosome per cell.

Is DNA extracted from a strawberry pure?

This white stringy stuff is actually strawberry DNA – the molecule that stores the information of life in all cells. This DNA won't be particularly pure, as it will have a lot of cell proteins attached to it. ... The contact lens solution contains enzymes, called proteases, which break down proteins.

Where is DNA in strawberries?

This will further break open the cells. Within a few seconds, watch for the development of a white cloudy substance (DNA) in the top layer above the strawberry extract layer.

Which fruit produces the most DNA?

But when it comes to seeing which fruit or vegetable has the most DNA, it would be Plum because it had the most DNA out of all the fruits and when we compared it to the vegetable that had the most DNA out of all the vegetables, the Plum had more.

What fruits can you extract DNA from?

Experiment to purify DNA from fruit Bananas, kiwis and strawberries all work well. (Remove the skin of the bananas and kiwi, we just want the insides!) Step 2: In a separate bowl, mix the washing up liquid, salt and tap water. Stir gently trying to avoid making too many bubbles in the mixture.

Why can you extract DNA from a strawberry?

Ripe strawberries are an excellent source for extracting DNA because they are easy to pulverize and contain enzymes called pectinases and cellulases that help to break down cell walls. And most important, strawberries have eight copies of each chromosome (they are octoploid), so there is a lot of DNA to isolate.

Does strawberries have a lot of DNA?

And most important, strawberries have eight copies of each chromosome (they are octoploid), so there is a lot of DNA to isolate.

What is the best fruit to extract DNA from?

Experiment to purify DNA from fruit Bananas, kiwis and strawberries all work well. (Remove the skin of the bananas and kiwi, we just want the insides!) Step 2: In a separate bowl, mix the washing up liquid, salt and tap water. Stir gently trying to avoid making too many bubbles in the mixture.

What kind of DNA does a strawberry have?

Strawberries are octoploid, meaning that their cells each have eight duplicate copies of each chromosome. This gives the cells a lot of DNA, which means it is easier to extract a large amount of DNA that is visible to the naked eye. What’s the table salt for?

How do you get DNA out of strawberries?

Procedure. After you added the cold rubbing alcohol to the filtered strawberry liquid, the alcohol should have precipitated the DNA out of the liquid while the rest of the liquid remained in solution. You should have seen the white/clear gooey DNA strands in the alcohol layer as well as between the two layers.

What to ask students about DNA and strawberries?

See lab handout “Strawberry DNA Extraction” Questions: 1. Have students complete the “Student Response” worksheet. 2. Answer any questions from the list made at the beginning of class. Closure: 1. Ask students what they learned abou t DNA and strawberries. 2. Ask students where DNA is found. 3.

What happens to DNA when you mix alcohol and Strawberry?

Take care not to tilt or tip the test tube; do not mix the two liquids. Observe the line between the strawberry mixture and the alcohol. You will notice a white thread-like cloud appearing at this line. This is strawberry DNA. The DNA will clump together and float to the top of the alcohol layer.
