Answer #1

I believe the correct answer to be:

Option C) The level of expression of the gene is altered.

As the sequence of the promoter determines how strongly the RNA polymerase binds to the promoter and starts the transcription and if there is a muation in this sequence, it will likely affect the amount of the mRNA that will be produced for that promoter.

feel free to leave a comment down below for any further query. good rating would be appreciated if you find my answer helpful. thank you.

Q2 An open reading frame (ORF) is a section of codons that begins with a start codon and ends with a stop codon. Each codon specifies for a specific amino acid. ORF is the part of a gene that after transcription into an mRNA gets translated into a protein. With the help of several translation factors and enzymes, ribosomes translate mRNAs into proteins. The following DNA sequence contains a complete open reading frame (ORF) of a short transcriptional unit. The...
