8) The following DNA strand is a template strand of a prokaryotic gene. Asterisk indicates the transcription initiation site. a) Underline the promoter region by a dotted line. b) Deduce the nucleotide sequence of mRNA for this gene. c) Underscore the leader sequence in mRNA and box the initiation codon. d) Show 5' and 3' ends of the template strand and mRNA.

mRNA: 3`- CCGUGGCAGCGAUAAUGCUUCAGCGACUGCCUAGAUGGGGCCUAAA --5`
The promoter sequence : at -10 upstream TATTAC
The leadersequence in mRNA at the initiation codon: initiation starts at 3` - CGA-5`.
