9. Below is an electron micrograph of a gene that is being transcribed. The DNA strand runs horizontally

with RNA transcripts extending vertically outward. (6 pts)

DNA template

a. Draw an arrow to indicate the direction of movement of RNA polymerases along the length of

DNA strand. Why did you choose this direction?/nb. Below is a partial sequence of the gene that is being transcribed in the schematic above. Its

orientation is the same as that shown in the schematic. Which strand is the template strand, the

top or the bottom strand? Explain your choice.

5'ACTCGATGCTAG3'

3'TGAGCTACGATC5'

c. Give the sequence of the mRNA that would be transcribed from the above sequence and label

its 5' and 3' ends.
