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.
To address this issue, the National Institutes of Health initiated the Human Genome Project in 1990. Led by James D. Watson (one of the co-discoverers of the chemical makeup of DNA) the project's 15-year goal is to map the entire human genome (a combination of the words gene and chromosomes).
