All of these questions are highly doable! But you've written too many in one topic. To tackle the one below, divide the number of amino acids by 3 (three nucleotides define an amino acid).

A particular eukaryotic protein is 300 amino acids long.  Which of the following could be the number of nucleotides in the DNA that codes for this protein?


Question 12 options:

 

A)  3  
 
 

B)  100  
 
 

C)  300  
 
 

D)  900  
 
 

E)  1800
