Anaphase
Telophase
A researcher is studying mitosis in a novel diploid organism with 2n = 16 chromosomes. During metaphase, a drug is applied that inhibits the separation of sister chromatids but allows the cell to progress through anaphase and telophase. At the end of this aberrant cell division, what is the most likely chromosomal composition of the resulting daughter cells?
Two diploid cells (2n=16) each
One diploid cell (2n=16) and one cell with no chromosomes
One tetraploid cell (4n=32)
Two cells with 8 chromosomes each
Which of the following accurately describes the role of motor proteins during anaphase of mitosis?
Kinesins move chromosomes towards the minus ends of kinetochore microtubules, and dyneins move chromosomes towards the plus ends.
Dyneins move chromosomes towards the poles along kinetochore microtubules, while kinesins are involved in cytokinesis.
Kinesins move chromosomes towards the plus ends of kinetochore microtubules, while dyneins move the poles apart by acting on astral microtubules.
Both kinesins and dyneins move chromosomes towards the poles along kinetochore microtubules, with kinesins acting on the leading edge and dyneins on the trailing edge.
