Hypothesis
Can the gaps in the human chromosome 22 sequence be closed using a combination of sequencing techniques?
Conclusion
The study successfully closed 8 out of 11 gaps in the human chromosome 22 sequence, generating 1.018 Mb of new sequence.
Supporting Evidence
- Eight out of eleven gaps in the human chromosome 22 sequence were successfully closed.
- Over 1.018 Mb of new sequence was generated.
- Six of the seven gaps in 22q13 were closed using a combination of techniques.
Takeaway
Scientists worked hard to fill in missing pieces of the human chromosome 22, adding a lot of new information to our understanding of it.
Methodology
A combination of chromosome walking, whole chromosome shotgun sequencing, comparative genome analysis, and long PCR was used to close gaps.
Limitations
Some gaps remain unclosed, particularly those associated with repetitive sequences.
