 I filled out a few boxes for you to start you off. I also gave you a direct research sources for some animals that will take you to the necessary information. 
This is what I have so far as examples for you. Again, I said I wouldn't do all of your work for you, however, I will help you through your research and graph. 
 
        
        
        
First i would like to discuss the design with the head of the construction crew that are capable of understanding the engineering part, then ask him if the design is feasible, if its realistic, if it is safe to be house and if it is safe to work on by the workers. and it would be his task to deliver it the others
        
             
        
        
        
Answer:
TAGTC
Explanation:
There are four different nucleotides in DNA: adenine, thymine, cytosine and guanine. 
The bases pair like so: 
A with T (adenine with thymine) 
C with G (cytosine with guanine) 
The DNA sequence given is : 
ATCAG 
Match As with Ts, Ts with As, Cs with Gs and Gs with Cs. 
The sequence of nucleotides that would bond with the sequence above is: 
TAGTC
