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.
Mapping is the construction of a series of chromosome descriptions that depict the position and spacing of genes, which are on the DNA of chromosomes. The ultimate goal of the Human Genome Project is to decode, letter by letter, the exact sequence of all 3.2 billion nucleotide bases that make up the human genome. This means constructing detailed genetic and physical maps of the human genome.
