1. Do you think some of the plants will have more DNA than others? why or why not?
2. Do you thinkit would be easier to extract the DNA from a strawberry or from a human? Explain your choice.
plsss help us

Answer:
1)One explanation for the large increase in gene number during angiosperm evolution is gene duplication. It has been shown previously that the retention of duplicates following small- and large-scale duplication events in plants is substantial.
2)Strawberries are chosen for this particular experiment because strawberry cell has eight copies of the genome, and it would be easier to extract the DNA since it is a lot per cell whereas most of the organisms would only have one genome copy per cell. Chill the rubbing alcohol in the freezer.
Each little piece of a living thing, known as a cell, has DNA in it. In humans each of these cells have 2 copies of the DNA, but in strawberries each of these have 8 copies of the DNA (scientists call this octoploid). That means strawberries have 4 times as many copies of DNA as humans, making it 4 times easier to see!
Answer:
Do plants have unique DNA?
answer
Yes, they do have distinct genes in general, but what you may see as different plants can also sometimes be clones. For example Quaking Aspen Trees which commonly grow in clonal colonies. If you had a massive database of genetic material from plants you would be able to trace it.
