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.
Chromosomes [chromosome: One of the rod shaped bodies found in the nucleus of cells that contain genetic information (DNA).] are threadlike structures found in the nucleus of most cells (remember red blood cells have no nucleus and so these are not produced by mitosis).ll the cells in the body of a particular species contain the same number of chromosomes. Cell division, or mitosis, is the method of increasing the number of cells. Single celled organisms can reproduce in this way to make new organisms.
