Which of the following has the MOST similarity in nucleotide sequence?

Question

Quizplus · Accepted Answer

Sister chromatids are exact copies of each other, so they have the most similarity in nucleotide sequence. Homologous chromosomes and maternal/paternal copies of the same chromosome may have similar sequences, but they are not identical like sister chromatids. Nonhomologous chromosomes may have some similar sequences, but they are not closely related like sister chromatids or homologous chromosomes. Complementary strands of DNA have base-pairing rules, but they are not identical like sister chromatids.
