I'm in the process of writing a research paper for school. Looking back at the introduction of my original research proposal (which I'm using as a scaffold for my current paper) I realized that the use of "is" vs. "are" in one sentence might not be right, but I don't know how to deconstruct the sentence to figure it out.

The original sentence follows and the problematic word is bolded:

"Crucial to successful cell division is the alignment and subsequent segregation of chromosomes into daughter cells…"

Thanks a bundle!
