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 Human Genome Project set out to sequence the DNA of every human chromosome, thereby promising to advance knowledge of human biology and improve medicine. This project was huge in scale, as it sought to determine the order of all 3 billion nucleotides in the human genome. To reach this lofty goal, scientists developed a number of sequencing techniques that emphasized speed without too much loss of accuracy.
