What does martin luther king, jr. mean when he claims, "injustice anywhere is a threat to justice everywhere"?

Dr. Martin Luther King jr. was saying that if a person was being treated unjustly in one part of the world then it was a threat to the laws and justice system in every part. That all men should be treated equal and fair.

Okay, biology isn't exactly my strongest subject (it never has been), but i'm pretty sure the answer is nucleotides. dna is made up of nucleotides. each nucleotide contains a phosphate group, a sugar group, and a nitrogen base. there are four different nitrogen bases: adenine (a), thymine (t), guanine (g), and cytosine (c). a always pairs with t, and g always pairs with c.
