    2. 2. Prokaryotic Cell Reproduction <ul><li>Prokaryotes reproduce by _____________________-. </li></ul><ul><li>Produced identical offspring </li></ul><ul><li>First the DNA is copied </li></ul><ul><li>New cell membrane is added to pinch the cell into two _______________cells . </li></ul>
    3. 4. Eukaryotic Chromosomes What are chromosomes made of? _________________ What is a gene? _____________________ ___________
    4. 5. Which organism has the most chromosomes?__________least?___________
    5. 6. Human Chromosomes (karyotype) Is this a karyotype of a male or female? What is the difference between male and female?
    6. 7. Sets of Chromosomes <ul><li>Humans have 23 sets of two chromosomes </li></ul><ul><li>One of each pair came from each parent. </li></ul><ul><li>_ _____________ _ cells (body cells) all contain 46 chromosomes </li></ul><ul><li>__ ____ __ chromosomes (sperm and egg) are haploid, they contain 23 chromosomes each. </li></ul><ul><li>When sex chromosomes combine they form a diploid _ ________________. </li></ul>
    7. 8. Chromosomal Mutations What do the different sections represent? What went wrong in each mutation? sickle-cell disease is caused by a single point mutation which encodes the amino acid valine rather than glutamic acid .
