Bioluminescence occurs through a chemical reaction that produces light energy within an organism's body. For a reaction to occur, a species must contain luciferin, a molecule that, when it reacts with oxygen, produces light. ... Many organisms also produce the catalyst luciferase, which helps to speed up the reaction
Hope i helped you :)

Answer:
b. Their presence is evidence of a defect in DNA replication, and therefore proof that a given disease is present
Explanation:
Single nucleotide polymorphisms (SNPs) result from point mutations and correspond to the position where there is alternation of nucleotides A, C, G, T at a minimum allele frequency of 1% in a given population. SNPs can be present in both coding and non-coding regions of the genome. As a nucleotide alternation is the result of a defect in DNA replication and these defects cause syndromes and diseases; we can say that single nucleotide polymorphisms are evidence of a defect in DNA replication and therefore proof that a particular disease is present.
B. The two groups share a relatively recent common ancestor.
(A. Cannot be true because human and monkeys are not that closely related
C. Cannot be true because it is not explicitly indicated by the DNA evidence provided by the excerpt
D. Cannot be true because monkeys would be extinct if human replaced them)
