All living organisms are composed of cells.
Earlier in the course, you explored cell structure and function. This week, you learn about how cells replace themselves and pass on their genetic traits.
The cells in your body undergo a type of cell division known as mitosis to replace damaged cells and enable new growth. In order to reproduce, human beings and most animals use the type of cell division called meiosis.
For this week’s Assignment, you complete a virtual lab in which you explore mitosis and meiosis. You then learn about the impact a mutation can have on either of these processes. Finally, you examine tissue samples in a virtual biopsy lab and write a lab report based on your analysis.
Review Chapter 6, “Reproduction at the Cellular Level” including:
How mitosis and meiosis compare
What a mutation is
What cancer is and what causes it
The causes and effects of various mutations
