Q: Duplicated chromosomes are composed of two sister what?


Read this paragraph and choose the correct option from the provided answers:

Duplicated chromosomes are composed of two sister chromatids. Chromosomes are compacted using a variety of mechanisms during certain stages of the cell cycle. Several classes of protein are involved in the organization and packing of the chromosomal DNA into a highly condensed structure. The condensing complex compacts chromosomes, and the resulting condensed structure is necessary for chromosomal segregation during mitosis.

 Choices:

- karyotypes

- eukaryotes

- nucleotides

- chromatids


A:
chromatids
