Answer:
Chromosome
Step-by-step explanation:
As the cells prepare for cell division, several events occur. During the prophase of mitosis, the thin threads of chromatin are condensed into rod-shaped visible structures. The process of compaction of chromatin gives rise to chromosomes. Chromosomes are rod-shaped structures made up of DNA and packaging proteins. Since DNA replication has already occurred during the S phase of interphase, each chromosome has two sister chromatids.
