A competing commercial effort to sequence the human genome was initiated by the company Celera in 1997 . How was their approach different from the Human Genome Project?
A. They generated overlapping clones from YAC and BAC libraries that were identified by hybridization and organized into long contiguous stretches called contigs.
B. Libraries of individual chromosomes were generated and overlapping clones were isolated before sequencing.
C. They used a whole-genome shotgun sequencing method that eliminates the step of assembling a physical map of the genome.
D. They used sequence tagged sites (STS) and expression sequence tags (EST) to order contigs prior to sequencing.
E. They sequenced the entire genome from one female donor.
