When curious kids find their way into regular liquid laundry detergent, the result is often nothing worse than an upset stomach. Laundry deteregent pods are presenting more serious symptoms. Along with vomiting, lethargy, and delirium, some victims have stopped breathing. Eye injuries are another common hazard.
Histones are proteins that allow DNA to be tightly packaged into units called nucleosomes. The DNA wraps itself around the histones. Chromatin is made of DNA and proteins (Histones). Chromatin is used to give structure to a chromosome.
Nucleus [edit]. The nucleus contains most of the genes in the eukaryotic cell; some genes are located in mitochondria and chloroplast. It is generally the most conspicuous organelle in a eukaryotic cell. The nuclear envelope encloses the nucleus, sparating its contents from the cytoplasm.The nuclear envelope is a double membrane, each a lipid bilayer with associated proteins. The envelope is perforated by pore structure that are about 100nm in diameter.he nuclear envelope encloses the nucleus, sparating its contents from the cytoplasm.
