(B) Two alternative strategies were used to complete the genome - top down and bottom up
(C) The public project used a mapping strategy to limit the total sequencing required
(D) The Celera group, led by Craig Venter, used a shot gun sequencing strategy
Explanation:
As the project was unable to sequence all the DNA that was found in the human cells, the first draft was <u>made in June and complete in the end referred to as a working draft and made on the basis of the final sequencing and mapping of the human genome.
</u>
The <u>draft included the alternative strategies for the completion of the bottom up and top up of the genome code and has a mapping strategy</u> that limited the total sequencing needs.
