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.
Ribosomes are produced in the nucleolus as well. As the control center of the cell, the nucleus stores all the chromosomal DNA of an organism. The region between the cell membrane and the nucleus of a cell is the cytoplasm. It is a gel-like substance which is part of the cell and holds important organelles. The cytoplasm is the site for many biochemical reactions necessary for maintaining life. It is the place where cell expansion and growth take place.
