Quizplus · Accepted Answer

Step 2 represents a pair of duplicated homologous chromosomes after G1. This is because in the S phase of interphase, DNA replication occurs, resulting in the formation of identical sister chromatids that are attached at the centromere. These sister chromatids form a pair of duplicated homologous chromosomes after G1.
