Scientists Don't Always Want to Share Their Data

Scientists don't always want to share their data. Why do you think they are willing to put DNA and protein sequences in a national database open to everyone?

A) The government makes them do it.
B) Because these data come from living things, none of it is private anyway.
C) There is so much information there, the odds of anyone actually using anyone else's data are remote.
D) There is so much information in one DNA sequence that it would be impossible for a single scientist to store it all him- or herself.
E) There is so much information there that the more people are free to investigate questions using it, the more useful answers we will find.
