Which are replicated during interphase? sister chromatids chromosomes centromeres nuclei
sweet [91]

The right answser is Chromosomes.

After DNA replication during cell cycle interphase, the chromosomes are composed of two identical chromatids attached at the centromere. Each chromatide is formed of a molecule of DNA (the nucleofilament) associated with proteins, the histones, around which it winds to form nucleosomes. At the ends of each chromatid are telomeres, consisting of repetitive DNA sequences that provide protection for chromosomal endings. Telomeres and centromere do not encode genetic information, it is non-coding DNA.
