Final answer:
A traditional genomic DNA extraction requires a sample the size of a quarter, and when comparing DNA quantities in similarly sized strawberries and kiwis, strawberries are expected to yield more DNA due to their octoploid nature, as opposed to kiwis that are diploid.
Step-by-step explanation:
The DNA test that typically requires a fairly large sample, such as a pool of blood the size of a quarter, is a traditional genomic DNA extraction procedure. These methods often need a considerable amount of starting material to ensure that enough DNA is present to be accurately measured and analyzed.
When forming a hypothesis about whether you could detect a difference in DNA quantity from similarly sized strawberries and kiwis, one would have to consider the cellular makeup and density of the fruits. Strawberries are known to have large genomes and are octoploid, meaning they have eight sets of chromosomes. In contrast, kiwi are diploid, with just two sets of chromosomes. Hence, when comparing similar sizes, one might expect the strawberry to yield more DNA.
To test your hypothesis, you should perform an experiment where you isolate the DNA from both fruits and compare the quantities. It is important to conduct this experiment at least three times for each fruit to ensure that the data is reliable. This approach allows for the assessment of the hypothesis through a hands-on investigation.
Regarding the question about whether a kiwifruit and strawberry that are the same size also have approximately the same amount of DNA, based on the genomic characteristics of each fruit, the prediction would be that they do not. The strawberry is likely to have more DNA due to its octoploid nature compared to the diploid nature of the kiwifruit.
