WebChromosomes You will need to be able to: Explain what a chromosome is. Explain what a gene is. Understand how many chromosomes are in the nucleus of a cell. Most of your cells contain a nucleus, where your genetic material is stored as DNA. DNA is a long strand of genetic code (which you will learn more about later).
WebThe human sex chromosomes, called X and Y, are structures in human cells made up of tightly bound deoxyribonucleic acid, or DNA, and proteins. Those are molecules that contain the instructions for the development and functioning of all life forms, including the development of physical traits and body parts that correspond with each biological sex.
