Mitosis occurs in a series of tightly regulated stages. Disruption of any of these stages can hinder chromosomal transmission during mitosis. Suppose that vinblastine, a chemotherapeutic medication that specifically targets and disrupts microtubules, is applied to a cell culture undergoing mitosis. Which of the following best explains how this medication will affect the transmission of chromosomes to daughter cells?

A) The daughter cells will remain genetically identical to their parents because microtubules are only involved in degradation of the nucleus during prophase.
B) The daughter cells will not be genetically identical. Microtubules are involved only in alignment of chromosomes at the midline during metaphase and separation during anaphase.
C) The daughter cells will not be genetically identical because microtubules are only required for a process in which homologous chromosomes exchange genetic information during prometaphase.
D) The daughter cells will not be genetically identical because microtubules are involved in the formation of the spindle apparatus during prophase, attachment to the kinetochore during prometaphase, alignment of chromosomes at the midline during metaphase, and separation during anaphase.

Ascientist separates a population of mice into two groups. what would most likely increase the rate of speciation in this population. a. teach the two groups different tricks b. allow the two groups to breed with each other c. put the two groups in different environment d. have the two groups live in identical ecosystems

Mike has a problem with his testosterone. he is unable to produce enough. which will most likely be affected by his inability to produce testosterone? check all that apply.

Will mark brainliest i only need the ! 1.use ten beads and a centromere of one color to construct the long chromosome. use ten beads and a centromere of a second color to construct the second chromosome in the long pair. make a drawing of the chromosomes in the space below. 2. for the second pair of chromosomes, use only five beads. 3. now model the replication of the chromosomes. make a drawing of your model in the space below. part b: meiosis i during meiosis i, the cell divides into two diploid daughter cells. 4. pair up the chromosomes to form tetrads. use the longer tetrad to model crossing-over. make a drawing of the tetrads in the space below. 5. line up the tetrads across the center of your “cell.” then model what happens to the chromosomes during anaphase i. 6. divide the cell into two daughter cells. use the space below to make a drawing of the result. part c: meiosis ii during meiosis ii, the daughter cells divide again. 7. line up the chromosomes at the center of the first cell, one above the other. separate the chromatids in each chromosome and move them to opposite sides of the cell. 8. repeat step 7 for the second cell. 9. divide each cell into two daughter cells. use the space below to make a drawing of the four haploid cells
