Answer:A) UCAAGU
Explanation: Molecule 1 is a double-stranded DNA helix while molecule 2 is a single stranded RNA molecule.
DNA is copied into an RNA molecule in a process known as transcription. Transcription is catalyzed by RNA polymerase. During transcription, a DNA strand is used as a template for the synthesis of a complementary RNA strand. In base pairing, wherever adenine occurs in the DNA template strand, uracil occurs in the complementary RNA strand, wherever thymine occurs in the DNA template strand, adenine is found in the complementary RNA strand while wherever guanine is found in the DNA template strand, cytosine occurs in the RNA strand.
