What is "spacer DNA"? What is true of the sequences of these regions of DNA compared to the palindromic repeats?
a) Spacer DNA is non-functional DNA; It has the same sequence as palindromic repeats.
b) Spacer DNA is a coding region; It is complementary to palindromic repeats.
c) Spacer DNA is derived from foreign DNA; It is diverse compared to palindromic repeats.
d) Spacer DNA is a type of ribosomal RNA; It is smaller in size than palindromic repeats.
