Answer:
D. When you are analyzing DNA of organisms
Explanation:
Cladistics is focused on tracing common ancestors, which relies not only on physical characteristics but also DNA evidences. Cladistics is also known as modern taxonomy. Linnean taxonomy is more on the physical characteristics, which is also called traditional taxonomy. As technology progressed so did taxanomic categories, which allowed researchers to compare DNA to determine similarities in seemingly unrelated animals.

The answer is C - Recombinant DNA. Why?
A transgene is a gene or genetic material that has been transferred naturally, or by any of a number of genetic engineering techniques from one organism to another. The introduction of a transgene (called "transgenesis") has the potential to change the phenotype of an organism.
The structure is a helix structure.
The four bases are
adenine (A), guanine (G)
cytosine (C), and thymine (T).
The pairing are
Adenine (A) always pairs with thymine (T), and guanine (G) always pairs with cytosine
