Match the phases in the cell cycle to the events that occur in each phase.

The question is incomplete, but I will answer it generally. The cell cycle is divided into: interface, prophase, metaphase, anaphase, telophase and cytokinesis.

Explanation:

In the S phase of the interface, DNA is duplicated by making a copy. This forms daughter cells with identical genetic makeup. The interface option should match "DNA replicates".

During the karyokinesis phase, the cell nucleus division occurs, forming two nuclei with the same genetic makeup. The option should match "the core splits".

Finally, cytokinesis is the division of the cytoplasm in the final cycle of mitosis, this produces the separation of the cell into two daughter cells. The cytokinesis option should coincide with "the cytoplasm divides."

the backbone of the dna and rna compound is sugar phosphate.
