Unformatted text preview: genes are composed of DNA, DNA is present as very long molecules, the long DNA molecules are complexed with proteins and coiled and folded into a structure known as a chromosome the cell has a fairly simple method of ensuring the proper inheritance of its DNA (and hence genes) when it splits into two daughter cells. An excellent (though slightly out of date) external web site to visit for a description of the basic molecular genetics is The US Department of Energy's Primer of Molecular Genetics . (The Department of Energy is a big mover in the Genome World.) It takes many cell divisions to make a person from a single celled egg. In each of those divisions all the genes must be replicated and passed to each daughter cell. For the remainder of this lecture we will concentrate on the process of cell division mitosis and on the structures known as chromosomes ....
