Final answer:
DNA contains the code for tiger shark characteristics through its arrangement of nucleotides in specific sections called genes.
Step-by-step explanation:
DNA contains the code for tiger shark characteristics through its arrangement of nucleotides. These nucleotides, which include cytosine, thymine, adenine, and guanine, make up the genetic information stored in the DNA. Genes, which are specific sections of the DNA chain, contain the instructions for the development of traits in an organism.
In the case of tiger sharks, their DNA contains the specific genetic instructions that result in traits such as their unique skin pattern and characteristics like their ability to use electroreceptors in their snouts to locate prey. These traits are determined by the arrangement and expression of genes within the tiger shark's DNA.
