Transcription
1. What is transcription?
2. Where does transcription occur?
3. Describe the function of RNA polymerase –
4. Write the complementary mRNA for the following DNA template strands:
a. ATGCATTG
b. GGTCTAGG
c. TCGGATCG
d. TACGCGTA
5. This is a template DNA sequence: 3'AATCGCTAC5'. This is a partially-completed mRNA strand
transcribed from the DNA template: 3'GCGA5'. What is the next nucleotide that RNA
polymerase will attach?
6. What are two ways that messenger RNA is processed prior to translation?
7. What are exons?
8. Here are two related mRNA sequences: 5'UUUAGCGAGCAU3' and
5'UUUAGCCAUAAAAAAAA3'. How was the second sequence formed?
a. a tandem repeat mutation formed the second sequence
b. processing removed an exon and added a poly-A tail to form the second sequence
c. processing removed an intron and added a poly-A tail to form the second sequence
d. RNA polymerase matched up several incorrect nucleotide bases to the original
DNA as the second sequence formed
