changes in DNA sequence that are neither beneficial nor detrimental to the ability of an organism to survive and reproduce. In population genetics, mutations in which natural selection does not affect the spread of the mutation in a species are termed neutral mutations.
They are neutral because they do not change the amino acids in the proteins they encode.
Explanation:
Many other mutations have no effect on the organism because they are repaired before protein synthesis occurs. Cells have multiple repair mechanisms to fix mutations in DNA.
Chelation therapy is a method for removing heavy metals, such as mercury or lead, from blood. It's one of the standard treatments for many types of metal poisoning. Hope this helped :)
