Questions and Answers

What happens during S phase of interphase?

  • The cell grows physically larger and copies organelles
  • The cell separates its DNA during M phase
  • The cell synthesizes a complete copy of the DNA in its nucleus (correct)
  • The cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis

    • What is the function of kinetochore?

  • To duplicate a microtubule-organizing structure in S phase
  • To help separate DNA during M phase (correct)
  • To synthesize a complete copy of DNA in S phase
  • To make proteins and organelles in G2 phase

    • What is the prefix 'inter-' in interphase referring to?

  • The reorganization of contents during G2 phase
  • The growth of the cell during G1 phase
  • The duplication of DNA during S phase
  • The fact that it takes place between one mitotic phase and the next (correct)
