A schematic shows a dividing cell. The middle of the cell is slightly indented; it is pinching apart to form two separate, daughter cells. The chromosomes and important parts of the spindle apparatus are labeled.

Cells duplicate and condense their DNA prior to entering mitosis. During mitosis, chromosomes attach to a spindle of microtubules that distribute them equally to two daughter cells.

How a Cell Identifies DNA Errors

A new approach allows researchers to track the dynamic activity of the MutS repair protein at nanometer-scale resolution in live cells, bringing us closer to understanding exactly how a cell finds and repairs DNA mismatch mutations.

Chronic Absent/OASIS students--last year there were a handful of students that were absent all the time or would unknowingly miss weeks of school while transferring foster care or attending twilight school.  I think this is a great website that has "teacher" notes that students can study to keep up with the course.  I will probably refer a lot of students here.  I did not love all of the pages, but the mitosis/meiosis stuff was especially good for inheriting knowledge.
