Sally was analyzing samples of DNA. She had DNA samples from bacteria, a whale shark, a bald eagle, and a human. Just by looking at the structure and components of the DNA, what could Sally conclude?












A)
the eagle and shark would have very similar DNA



B)
the DNA of the human would have a more complex physical structure than the rest



C)
only the DNA of the bacteria would be coiled into a double helix, so she could identify it



D)
all DNA is made of the same components so there she would see no difference between the samples

btw the answr for yours is A bcuz TIDES aree drawn in and casted out by the Moon's gravitional pull.

ohh ohmyword thank u!!

Answer 4

wait one last question!..:

The Human Genome Project is devoted to mapping the general DNA sequence of our species. This could lead to the development of new medicines, as well as the possibility of using gene therapy to treat certain diseases.

However, there are some ethical issues surrounding the mapping of individual genomes. One concern is












A)
that your genes may change over time, making the project useless.



B)
that insurance companies could discriminate based on genetic make-up.



C)
that since this has never been done before, we should probably not do it now.



D)
that sequencing our individual genomes is so expensive, it is a counter-productive strategy.
