Vedclass · Answer

(A) During the $S$-phase of interphase,$DNA$ replication occurs,resulting in each chromosome consisting of two sister chromatids joined at the centromere.In mitosis,the chromosomes align at the metaphase plate,and each chromosome still consists of two chromatids.In meiosis $I$,homologous chromosomes pair up and align at the metaphase plate; each chromosome still consists of two chromatids.Therefore,in both mitosis and meiosis (specifically metaphase $I$),each chromosome consists of two chromatids.
