Because it can respire anaerobically, without oxygen.

The biggest reason for that her work is a success is because new ideas often develop from unsuccessful experimentation.
The scientific process not only relies on proper experimental methods and determination, but it also is dependent on the failures of the experiments of scientists. When experiments fail, other scientists obtain a guideline of what to do and what not do. This improves their own experiments and helps them move forward.

The DNA (deoxyribonucleic acid) is the double helical in structure. It has two anti parallel strands of long polynucleotides. The nucleotides are two purines ( adenine and guanine) and two pyrimidines ( thymine and cytosine). These purines and pyrimidines are attached with their complementary. Adenine pairs with the thymine with the two hydrogen bonds and the guanine pair with cytosine by three hydrogen bonds. The two strands are twisted which is responsible for the helical structure. The overall charge on the DNA molecule is the negative charge.
