Quizplus · Accepted Answer

A chiasma is a site of crossing over where non-sister chromatids pair up during meiosis and exchange genetic material. Histones are protein molecules that help package DNA into nucleosomes. A synapse is the junction between two neurons or a neuron and a muscle cell. A centromere is the part of a chromosome that links sister chromatids.
