6 things you should know about me: The nucleus has a double membrane (the nuclear envelope) around it. The nuclear membrane has pores allowing the movement of substances through it. The nuclear membrane joins up with the endoplasmic reticulum. The nucleus contains chromosomes which are made of DNA and associated proteins called histones. There may be at least one dark stained body called a nucleolus. The nucleus contains genes that hold the information needed to make proteins. kscience.co.uk/as/module1/nucleus.htm
