Lymph nodes are the filters along the lymphatic system. Their job is to filter out and trap bacteria, viruses, cancer cells, and other unwanted substances, and to make sure they are safely eliminated from the body. Axillary lymph nodes Larger Version.
Share. By Regina Bailey. Definition: Mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division. Chromatin is located in the nucleus of a cell. During prophase of mitosis, chromatin fibers become coiled into chromosomes with each chromosome having two chromatids joined at a centromere.
What forms to help attach and move chromatids to the opposite poles of the cells? The mitotic spindle fibers formed of tubulin subunits. What is the cell structure that joins two sister chromatids of a chromosome? The cell structure that joins two sister chromatids into one single  chromosome is called the centromere. This is at the center of the  sister chromatids.
