Correct answer - 120 for Thymine.
Why? - 320 Nitrogen bases. 
Cytosine = 40, Cytosine = Guanine.
Therefore Guanine = 40. 
320 - 80(Cytosine and Guanine)
240. 
Adenine and Thymine = ? 
Adenine = x and Thymine = x.
2x = 240.
X = 240/2
X = 120.
Adenine 120, Thymine = 120, Cytosine = 40 and Guanine = 40.

1. Two genetically identical copies of DNA 
2. Finds an error in DNA, removes the incorrect nucleotide and replaces it with a correct one.
3. It is used as a copy/ "template" for replication in order to have two identical copies of DNA.
4. DNA helicase unwinds DNA double helix and Topiosomerase ensure there isn't too much unwinding.
5. Replication has a built on proofreading system - DNA polymerase removes the incorrect nucleotide and replaces it with a correct one.
        
             
        
        
        
Foreign invaders have proteins called antigen, which antibodies lock onto to neutralize. The foreign proteins are different from proteins in our own body, so the immune system can recognize them and finally eliminate them.
