They called their theory “sea floor spreading.” The theory explains that as the sea floor spreads, the tectonic plates are pushed and pulled in different directions
Answer:
Spindle fibers move chromosomes during cell division by attaching to chromosome arms and chromosome centromeres. A centromere is a specific region of a chromosome where duplicated chromosomes are joined. The identical, joined copies of a single chromosome are known as sister chromatids. The centromere is also where specialized protein complexes called kinetochores are found.
