I apologize but with no problem I can't help :(
Answer:
The answer is B and D.
Explanation:
PKA ( Protein Kinase A) is an enzyme which becomes active with the presence of cAMP molecules in the cell and the cAMP molecules need to bind to R subunits to become active which happens at a ratio of 1:2.
The example given in the question states that the Ro sububit can bind to 8 molecules of cAMP rather than the conventional 2.
This means that the activation of the Ro subunits is harder than the activation of R subunit because of the requirement of higher cAMP concentrations.
B is correct, full activity of PKA with Ro subunits needs a higher concentration of cAMP.
Because Ro binds to eight units of cAMP, the dynamic range of activity of PKA with Ro is going to be over a wider range of cAMP concentration.
I hope this answer helps.
Active transport is the process that moves particles across a membrane that requires energy. This is because it moves particles from a low concentration to a concentration that is higher.

Answer:
Translation will not occur.
Explanation:
The start codon is responsible for the initiation of translation in both prokaryotes and eukaryotes. AUG is the start codon in both which code for methionine in eukaryotes and formyl methionine and prokaryotes.
Therefore if the starts codon becomes mutated than the tRNA would not able to recognize the initiation codon and no methionine would be added as the first amino acid so the translation process might not start and no protein forms. Then the ribosome scans further for the next start codon to start translation.
