2. Thymine with Adenine & Cytosine with Guanine 3. The Dna double helix must unwind near the gene which is supposed to get transcribed. 4. RNA polymerase 5. Uracil with Adenine & Cytosine with Guanine 8. Nucleotides 9. RNA polymerase 10. Dna - 2 strands MRNA - 4 strands 11. MRNA is an intermediary between the genetic info in Dna and the sequence of amino acids in proteins
