5’ UTR stabilizes and controls translation
Introns are in original mRNA but then chopped out
coding sequence is just one part of mRNA
Question: Which of the following is/are found in the mature ﬁnal mRNA?
2. 5’ UTR
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
