If you haven't done that, well you can assign old flights to the account but not really old ones. Anything older than 2 weeks will probably not be accounted for and you won't be able to get miles from those flights into the account.
The Human Genome Project was started in 1990 with the goal of sequencing and identifying all three billion chemical units in the human genetic instruction set, finding the genetic roots of disease and then developing treatments. It is considered a megaproject because the human genome has approximately 3.3 billion base-pairs.
So the major goal of these groups and organizations is to complete a genetic map of the human genome as soon as possible. There are other goals such as the mouse but the most exciting and anticipated one is that of the human genome.
