Cell Cycle and Cell Division NEET MCQ
Which of the following is not a phase of the cell cycle?

Answer: d) none of these
The spindle fibers are composed of which protein?
a) Actin
b) Myosin
c) Keratin
d) Tubulin
Answer: d) Tubulin The spindle fibers are composed of tubulin proteins. Tubulin is the protein building block of microtubules, which are the primary components of spindle fibers. During mitosis, spindle fibers are responsible for separating the duplicated chromosomes into two daughter cells by attaching to the chromosomes and pulling them apart. Tubulin is also involved in other cellular processes, such as maintaining cell shape and intracellular transport.

During which phase of the cell cycle does DNA replication occur?
a) G1 phase
b) G2 phase
c) M phase
d) S phase
Answer d) S phase The S phase, also known as the Synthesis phase, is the phase of the cell cycle where DNA replication occurs. During this phase, the cell replicates its genetic material (DNA) to prepare for cell division in the next phase, M phase. The replicated DNA ensures that each daughter cell will have an identical copy of the genetic material.
Which of the following is not a function of the centrosome?
a) Organization of microtubules
b) Formation of the spindle fibers
c) Separation of sister chromatids
d) Production of ATP
Answer: d) Production of ATP

b) Two cell divisions
c) Three cell divisions
d) Four cell divisions
Answer: b) Two cell divisions

Which of the following is not a type of cell division?
a) Mitosis
b) Meiosis
c) Binary fission
d) Budding
Answer: d) Budding
Which of the following is not a phase of meiosis?
a) Prophase I
b) Metaphase I
c) Anaphase I
d) Telophase II
Answer: d) Telophase II Telophase II is not a phase of meiosis. Meiosis consists of two rounds of cell division, meiosis I and meiosis II, which together result in the production of four haploid daughter cells. Each round of meiosis includes four phases: prophase, metaphase, anaphase, and telophase.
