It is not always easy to locate or identify genes based on cDNA. How is this problem created by the differences between cDNA and DNA with respect to a given gene?
What will be an ideal response?
cDNA is made from mRNA, which in eukaryotes is processed transcript with exons removed. The original gene may have many exons, and if so, the cDNA may little resemble it.
