Answer: Option D) 1:4
Explanation:
Recall that the sum of all nitrogenous bases in the DNA nucleotide is equal to 100%. And specific base pairings of Adenine to Thymine (A=T), and Cytosine to Guanine (C=G) must be equal.
So, the percentage of Adenine equal thymine, and that of cytosine equals guanine.
Now, A + T + C + G = 100%
So, if adenine makes up 10% of the DNA nucleotides, then thymine is also 10%.
Then, 10% + 10% + C + G = 100%
20% + C + G = 100%
C + G = 100% - 20% = 80%
Thus, divide 80% by 2 to obtain the individual percentage of cytosine and guanine. Each will take 40%
Ratio Adenine to Guanine is 10% to 40%
or 1:4 in simplest form 
 
        
                    
             
        
        
        
Answer:
Cysteine
Explanation:
<u>Determine the Amino acid that is primarily involved in Binding </u>
The Amino acid that is primarily involved in Binding is Cysteine. while the other Amino acid ( i.e.  Histidine ) will be involved in Catalysis.
since the enzyme is functional at pH 6 to 8. and Cysteine has a pH of 5, it should be deprotonated and used primarily for Binding .
