How many cells do you think there are in your body? 1b. How do you think a single cell developed into all the cells in your body? Before you learn how new cells are made, we need to briefly review chromosomes and genes. Each chromosome contains a long molecule of DNA. Each DNA molecule contains many A gene is a segment of a DNA molecule that the instructions for making a protein. Many of these proteins are needed for normal cell structure and function. 2. Explain why each cell needs to have a complete set of chromosomes. Include genes and proteins in your answer.
