Different groups of people have responded to feminism, and both men and women have been among its supporters and critics. Among American university students, for both men and women, support for feminist ideas is more common than self-identification as a feminist.
Sister chromatids are the two identical halves of a single replicated eukaryotic chromosome. They are joined at the centromere (see diagram at right) and are genetically identical because, during interphase, they are produced from the two complementary strands of a single duplex DNA molecule (more about replication >>).
Compare sister chromatids to homologous chromosomes, which are the two different copies of a chromosome that diploid organisms (like humans) inherit, one from each parent.
