Answer:B) UCGAAU
Explanation: Molecule 1 is a DNA molecule while molecule 2 is an RNA. In DNA bases present are Cytosine, Guanine, Adenine and Thymine. During pairing, Guanine pairs with Cytosine while Adenine pairs with Thymine. Bases present in an RNA molecule are Adenine, Uracil, Guanine and Cytosine. During pairing, Adenine pairs with Uracil which Guanine pairs with Cytosine.
