Around how long is the longest fragment of baby guppy DNA?

One-fourth of an inch long

Explanation:

I hope that helps!!! :)

one-fourth inch long

Explanation: DNA fragments are negatively charged, so they move towards the positive electrode.

Because all DNA fragments have the same amount of charge per mass, small fragments move through the gel faster than large ones.

Gel electrophoresis is a technique used to separate DNA fragments according to their size.

answer: the answer is b

"1. it should be, it has been for about 20 years, and it's really not much different in the end than breeding animals to have particular traits. there are always concerns about genetically engineered animals/plants affecting the environment in unexpected negative ways, but i can't think of an example where the fears didn't turn out to be baseless.  

first, as you point out, it would be a great advance in pharmacology, to be able to tailor drugs and their doses to me. the pros involve better medical treatment. the cons involve privacy issues like insurance companies denying coverage to people with genetic risk factors. looking at dna markers wouldn't affect the frequency of genetic diseases, but it would allow detection of them earlier. and ok, actually i suppose that if people used this information to avoid having children with genetic diseases, some might decrease in frequency."
