blagie [28]

Answer:

I've responded to each scenario individually, please see below:

1. mutation that prevents ribosome binding to the mRNA

No transcription occurs

2. 5' UTR mutation that changes region 1 tryptophan codons into alanine codons

Transcription when alanine is low

3. mutation that creates a stop codon in region 1 of mRNA 5' UTR

Transcription occurs, a truncated protein will be made during translation

4. deletions in region 2 of the mRNA 5' UTR

Transcription occurs, region 1 and 2 might get paired together

5. deletions in region 3 of the mRNA 5' UTR

Transcription occurs, region 3 and 4 could combine to form a hairpin loop structure

6. deletions in region 4 of the mRNA 5' UTR

Transcription occurs, region 3 and 4 could combine to form a hairpin loop structure

7. deletion of the string of adenine after region 4 of the mRNA 5' UTR

Transcription occurs, however, it will not be as stable a molecule because of losing its polyA tail

Hope that answers the question, have a great day!
