Final answer:
MLST can identify if two microbes are closely related by comparing their DNA sequences at multiple specific loci.
Step-by-step explanation:
MLST stands for Multi-Locus Sequence Typing, a technique used to determine the relatedness of different microbes. One way MLST can identify if two microbes are closely related is by comparing their DNA sequences at multiple specific loci, or regions of the genome. If these DNA sequences are highly similar or identical, it suggests that the two microbes share a recent common ancestor and are closely related. For example, if the DNA sequences at several loci match perfectly between two microbes, it indicates a high level of relatedness.
