If a cell does not go through the s phase of the cell before mitosis, what might be wrong with the daughter cells

The chromosomes will be unevenly split among the daughter cells.

Explanation:

Mitosis is the process of cellular division whereby a cell gives rise to two genetically identical daughter cells. Mitosis occurs in stages, however, prior to the mitotic process is a phase called INTERPHASE. The interphase further contains another stage called Synthesis phase or S-phase.

In the synthesis or S-phase, replication of the DNA occurs in each cell. That is, DNA duplicates in each cell to form sister chromatids. The aim of this is to ensure that the genetic material or chromosome becomes evenly distributed among the two daughter cells that are to be formed during mitosis.

However, If a cell does not go through the S phase before mitosis, it means that the daughter cells will not contain an even distribution of chromosome.

dna is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).

substitution is the answer in this case
