The answer that accurately reflects the relationship between transcription factors, polymerase affinity, and protein levels is:
**Polymerase affinity has a greater influence because you cannot start reading mRNA without it.**
While positive transcription factors are important for initiating transcription, the actual process of creating mRNA (which is then translated into proteins) relies heavily on the ability of RNA polymerase to bind to the DNA and carry out transcription. Without polymerase binding and activity, no mRNA would be produced, regardless of transcription factor presence. Therefore, polymerase affinity is crucial for protein synthesis.

The correct response is:
**base pair deletion**
In this case, the normal allele has more base pairs than the mutated form, indicating that some base pairs have been removed from the DNA sequence, which is characteristic of a deletion mutation.

Answer
A DNA codon that codes for a certain protein undergoes a substitution mutation. The new codon codes for the same amino acid as the original codon. What is the most likely effect of the mutation?(1 point)
Responses
The mutated codon produces a different protein than the original codon and causes a disease because the protein does not function properly.

The correct response is:
**The mutated codon produces the same protein as the original codon and does not cause a disease.**
This situation describes a synonymous mutation (or silent mutation), where a substitution in the DNA sequence does not change the amino acid sequence of the protein due to the redundancy in the genetic code. As a result, the protein remains the same and is likely to function normally, thus not causing a disease.

The correct response is:
**post-transcriptional control.**
Post-transcriptional control in prokaryotes involves mechanisms that affect the mature mRNA after it has been transcribed but before it is translated into protein. This can include processes like mRNA stability, splicing (if applicable), and the presence of regulatory RNAs.
