In a transcription unit, where region “A” is most upstream, and is part of the promoter, while region “B” is a region transcribed but not in the protein product, and “C” is found in the final mRNA product:
Question 44 options:
1)
a mutation in a consensus sequence of region "A" would result in a shorter than expected RNA transcript
2)
a mutation in region "A" would not affect transcription, as only regions "B" and "C" are included in the RNA transcript
3)
a deletion in region "A" would result in reverse transcription of "B" and "C"
4)
a deletion in region "A" would possibly result in the transcript not being produced
5)
a mutation in region "A" would not affect transcription, as other regions of "A" would be unaffected and permit transcription
