Solution

The correct option is C Both A and B
The α-like globin genes are located on chromosome 16, whereas the β-like globin genes are on chromosome 11. The latter results were obtained by hybridizing a solution of total cellular DNA from the various somatic hybrid cells to radioactive cDNAs, synthesized from α- and β-globin mRNAs by reverse transcriptase.
So, the correct answer is 'Both A and B.'
