Question

4. Which of the following statements is true when thinking about chromosome movement? Microtubules attach to the kinetochores during early prophase. The microfilaments pull the chromosomes back and forth until they align in a plane along the equator of the cell, which is called the longitudinal plane. Astral microtubules attach to the chromosomes and move the chromatids. The kinetochore is composed of proteins that assemble on the centromere to provide a site for the microfilaments to attach. One mechanism for movement is the use of motor proteins, kinesin and dynein by kinetochores.
