Shotgun sequencing is a very fast process for finding the nucleotide sequence of a genome. The downside is that repeat sequences are poorly interpreted.
Step | Overview |
---|---|
Isolate | Isolate chromosome from a homogeneous population. |
Digest | Digest into 150kb sequence fragments. |
Clone | Clone fragments into bacterial artificial chromosomes (BACs). |
Transform | Transform BACs into recipients. |
Screen | Screen for transformed colonies (selective media, like Xgal or CAM). |
Sequence | Sequence the inserts. |
Assemble | Assemble genome based on overlapping sequences. |
Annotate | Genome annotation using BLAST (Basic Local Alignment Search Tool) |
