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.
The first goal is to complete the sequencing of the human genome and to make it publicly available to researchers so they can all work together to better the human condition. Included in this goal is to improve technology so that there is a more efficient way of sequencing DNA.
