I wasn't sure where I was suppose to write this Ms.Brant so it's gonna go here.lol
The article you had us read questioning the need for 2 spindles during cell division was an interesting one.
Abstract:
A mandatory step of cell division is pulling apart the chromosomes to make the daughter cells. Scientists know that the spindle-like structures formed by polymerized tubulin plays an important role in cell division. The Iowa State team, led by Kristen Johansen, has found a new spindle made up of proteins from the nucleus. By using high tech. microscopes they can tell it is in fact a real spindle. Many things are still unknown about the interactions between the microtubules pull the chromosomes but the new nuclear spindle structure may be able to provide the answers to many of these questions. The team hopes this will help explain the abnormal cell division in cancer cells. That will be awesome because once they understand it creating a treatment for it will be a lot more possible.
Vocabulary:
tubulin- either of two globular proteins that form the structural subunits of microtubules
segregation- seperation
