Promoter 2. 5’ UTR 3. Exons 4. Introns 5. 3’ UTR Answer: 2, 3,5 Promoter is not transcribed, so it is not an element in mRNA Strands are opposite and complimentary to eachother. When RNA binds to DNA, two strands must split apart. This is called a DNA:RNA hybrid Strands are stuck together through hydrogen bonding in the bases. Same bases in DNA and RNA except RNA has Uracil, instead of Thymine DNA has H coming off 3’ end RNA has OH coming off 3’ end • makes DNA stab
