Hypothesis
The study aims to construct a BAC library for the giant panda and map specific genes to their chromosomes.
Conclusion
The first large-insert genomic DNA library for the giant panda has been constructed, aiding in the understanding of this endangered species.
Supporting Evidence
- The BAC library contains 198,844 clones with an average insert size of 108 kb.
- Ten BAC clones were mapped to 8 pairs of giant panda chromosomes using FISH.
- The library represents approximately seven equivalents of the giant panda haploid genome.
Takeaway
Scientists made a big library of panda DNA to help learn more about pandas and where their genes are located.
Methodology
A BAC library was constructed using genomic DNA from a male giant panda, and genes were mapped using fluorescence in situ hybridization (FISH).
Limitations
Only ten genes were mapped due to difficulties in preparing high-quality chromosome samples.
