MCB 150 CERTIFICATION EVALUATION
2026 PRACTICE SOLUTION TESTED.
⫸ Gamma Tubulin. Ans- Source for new MTs, Platform for new MT
dimers
⫸ Dynein. Ans- Motor protein that moves towards the minus end
⫸ Kinesin. Ans- Motor protein that moves towards the plus end
⫸ Axoneme. Ans- Structural unit of cilia and flagella, "9+2" pattern,
only has Dyneins
⫸ Basal Body. Ans- Minus ends of MTs of cilia and flagella are
anchored into this structure
⫸ Lamin B. Ans- Stay bound to the nuclear membrane during prophase
⫸ Lamin A & C. Ans- Do not stay bound to the nuclear membrane
during prophase
⫸ Kinetochore. Ans- place of microtubule attachment on chromosomes
, ⫸ Anaphase A. Ans- movement of sister chromatids to opposite poles
via kinetochore microtubules
⫸ Anaphase B. Ans- Spindles distnace themselves from each other
⫸ Cytokinesis. Ans- cytoplasmic division
⫸ Prophase. Ans- Disassemble MT array, Centrosomes move to
opposite poles, chromatin condenses, nuclear envelope dissociates
⫸ Prometaphase. Ans- Kinetochore MTs move pairs of sister
chromatids back and forth until they reach the metaphase plate
⫸ Metaphase. Ans- Pairs of sister chromatids are lined up on metaphase
plate, connection between sister chromatids broken
⫸ Anaphase. Ans- A: kinetochore MTs separate sister chromatids
B: polar MTs "push" and astral MTs "pull" poles
⫸ Telophase. Ans- Undo what was done during prophase
