Try each one before opening the answer. Each comes with a short explanation.
- Q1 · MDCAT 2011 · Cell Cycle & Division
When chromosomes uncoil, the nucleoli are reformed and two nuclei are the two poles of the cell; stage is known as
- A.Prophase
- B.Metaphase
- C.Telophase
- D.Anaphase
Show answer
Answer: C. Telophase — Telophase is the mitotic stage where chromosomes uncoil, nuclear membranes reform around the two sets of chromosomes, and nucleoli reappear at the two poles of the cell.
- Q2 · MDCAT 2010 · Cell Cycle & Division
Microtubules of spindle fibres are composed of a protein called
- A.Tubulin
- B.Actin
- C.Myosin
- D.Troponin
Show answer
Answer: A. Tubulin — Spindle fibre microtubules are composed of the protein tubulin.
- Q3 · MDCAT 2009 · Cell Cycle & Division
Internal program of events and sequences of morphological changes by which cell commit a suicide is collectively called:
- A.Necrosis
- B.Epistasis
- C.Metastasis
- D.Apoptosis
Show answer
Answer: D. Apoptosis — Programmed cell death, following an internal genetic program of controlled morphological changes, is called apoptosis.
