If scientists were trying to construct recombinant dna molecules, how would they do it?

Constructing recombinant DNA or rDNA scientists should combine both DNA from two different species.  Based on study, rDNA is possible if both DNA that should be combined should have the same chemical structure. Most o the DNA do have the same structure they only differ in nucleotide sequence. 

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
