If you were to treat sperm precursor cells with an agent that completely destroys microtubules (and ensures that they don't reform) at the start of metaphase I, how would this affect meiosis?

A. This would prevent kinetochores from forming on either side of the centrosome during meiosis I.
B. Meiosis I would be interrupted, but meiosis II would proceed normally, since microtubules are not required during this stage.
C. Homologous chromosome pairs would not line up at the cell's center, and the rest of meiosis would not proceed normally.
D. This would only affect the separation of homologous chromosomes during anaphase I, but would not cause any changes to telophase I or subsequent cell division.

Option C

Explanation:

Treating the microtubules with an agent that will disturb the function of the microtubles that function in the formation of the spindle assembly (thing helps in the movement of chromosomes to opposite poles) will bring about non allignment of the homologous pairs of chromosomes and giving rise to a disordered dispersion of chromosomes in the cell leading to cell arrest and might eventually result in apoptosis of the cell.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.
