Consider a pair of sister chromatids joined at their centromeres in a cell that has completed S phase in preparation for entering mitosis. What is the best description of the DNA composition of these chromatids? O Both chromatids have a random mixture of DNA sequences from parental and newly-synthesized DNA strands. O One chromatid has two strands of parental DNA and the other chromatid has two strands of newly-synthesized DNA. O Each chromatid has one strand of parental DNA and one strand of newly-synthesized DNA. O Neither chromatid will contain parental DNA. O Neither chromatid will contain newly-synthesized DNA.

Consider how the image of a replicated chromosome below relates to DNA replication. Then, select the one true statement. Identical sister chromatids Both chromatids consist entirely of daughter strands. Each chromatid has a daughter strand and a parental strand of DNA. One chromatid consists of newly replicated DNA, whereas the other chromatid consists of parental DNA. Replicated chromosome

When DNA is distributed in prokaryotes to daughter cells following DNA replication: Both daughter cells contain only newly synthesized DNA. The DNA in each daughter cell contains one original, parental DNA strand and one newly synthesized, daughter strand. Each daughter cell contains DNA that is unique compared to the parental cell. None of the given answers are correct One daughter cell contains both newly synthesized DNA strands, while the other daughter cell contains both the original, parental DNA strands.
