duplicate their chromosomal DNA prior to nuclear division
Explanation:
Mitosis and meiosis both involve duplication of a cell's DNA content. Each strand of DNA, or chromosome, is replicated and remains joined, resulting in two sister chromatids for each chromosome. A common goal of mitosis and meiosis is to split the nucleus and its DNA content between two daughter cells.
D. a cell wall.
reasoning: in a prokaryotic cell, they have no nucleus or organelles. a cell wall is the only answer that is neither of those.
