Aerobic respiration happens in the mitochondrion of eukaryotic cells. 
Anaerobic respiration does not use oxygen gas and happens in one process after glycolysis called Fermentation. 
The process used to make beer would be a kind of fermentation, Alcohol fermentation, I believe.
        
             
        
        
        
A strand of DNA having base sequence as ATG CGA. The complementary strand of DNA will be produced with base sequence as TAC GCT. In the double strand DNA nitrogenous bases paired in a specific manner, A (Adenine) always pair with T (Thymine) with double hydrogen bond or vice-versa and C (Cytosine) pair with G (guanine) with triple hydrogen bond or vice-versa.
