Why might scientists want to study the DNA of bananas or humans?

To measure the commonality between the two. Bananas and humans have a lot of DNA in common (as much as 60%, according to the source below).
By itself, some people might call this just a remarkable coincidence ... but together with commonalities between humans, or bananas, and all other life forms, we get a picture of what organisms are more closely related to what.
A second point is that this is not just *genes*, but *DNA*. In other words, there is a lot of DNA that is not involved in genes, or they are involved in genes that are active in bananas, but inactive in humans ... so these commonalities are not just related to useful functions. So much of this shared DNA cannot be explained as deriving from shared function (as one or both organisms don't require this function at all). So it can only be explained as evidence of shared ancestry ... both organisms have inherited genes from an ancestor, regardless of whether it is actually used by the organism.

you may desire to blend any 2 samples of DNA collectively, yet they'd not do something. this is plenty extra complicated than that. I in no way observed Batman previous, yet while it is something like what they did, this is unquestionably technology fiction. Jurassic Park is a miles extra real looking subject, a minimum of so some distance as getting dino DNA from petrified animals.

Banana And Human Dna

DNA is the same in bananas and humans. By DNA hybridization ( Taking one strand of banana DNA and matching it with a strand of human DNA ) we can tell how close we are genetically. If close, both strands would " stick " together, to a greater, or lesser degree. Chimps and our DNA does this. We are not that close to bananas. Though the universality of DNA/RNA is unchallenged by any evidence so far.

To keep their options open. Getting a grant to study human DNA would be really useful, but the competition would be fierce. Banana DNA, on the other hand, would be less useful, but also with less competition for grants, if they are available.

umm those are two completely different subjects that are completely non-related. maybe they would like to learn more about humans or banans... . duh.
