A researcher studying the Aedes aegypti mosquito, which transmits dengue fever in the Caribbean, observes rapid cell division in mosquito larvae tissues. At which stage of mitosis would the researcher observe the nuclear membrane reforming around two separate groups of chromosomes?

Q: How do I try a free CXC Biology question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live CXC CSEC Biology bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for CXC Biology students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Biology questions aligned to the CXC CSEC syllabus?

Every question is written against the published CXC CSEC Biology syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real CXC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

A researcher studying the Aedes aegypti mosquito, which transmits dengue fever in the Caribbean, observes rapid cell division in mosquito larvae tissues. At which stage of mitosis would the researcher observe the nuclear membrane reforming around two separate groups of chromosomes?

Accepted Answer

Telophase — Award 1 mark for identifying telophase. During telophase, the nuclear membranes reform around each set of chromosomes at opposite poles of the cell. A is incorrect — during prophase, the nuclear membrane breaks down. B is incorrect — metaphase involves chromosome alignment. C is incorrect — anaphase involves chromatid separation.

Answer

Telophase

Answer

Prophase

Answer

Anaphase

Answer

Metaphase
