According to the text, what is the consequence when sister chromatids separate during cell division?

  • A: They immediately re-attach to form a duplicated chromosome.
  • B: They are no longer called sister chromatids but are considered individual chromosomes, and the number of chromosomes effectively doubles.
  • C: They condense further to form a single, more compact chromosome.
  • D: The cell immediately exits cell division and enters a resting phase.

Explanation

The text states: 'Once the sister chromatids separate, they are no longer called sister chromatids but are considered individual chromosomes; this is the step that essentially doubles the number of chromosomes during cell division.'
