Answer:
Strands of replicated chromosomes.
Step-by-step explanation:
Chromatids are strands that have the genetic information in a replicated chromosome. In other words, they are the strands that form the chromosome that will later separate in the anaphase. Chromatids have a short arm and a long arm, telomeres, are nucleotide sequences at the end of the chromatids, and the centromere, which holds the two sister chromatids together.
