Question

What would be the most likely effect on the transcription of the trp structural genes for the mutation scenarios provided?.

Answer 1

1). Mutation that prevents binding mRNA 5’ UTR—(No Transcription occurs)
2). Mutation that changes region Hryptophon Codons into alanine codons— (Transcription when alanine is low)
3). Mutation that creates a stop codon in region 1 of mRNA 5’ UTR. (No transition occurs)
4). Deletions in region 2 of the mRNA 5’ UTR)
5). Deletions in the region 3 of the mRNA 5’ UTR. (Transcription occurs)
6). Deletions in region 4of the mRNA 5’ UTR. ( Transcription occurs)
7). Deletion of the string of adenine after region 4 of the mRNA 5’ UTR. (Transcription occurs).
