L1 Genes, Chromosomes, and DNA
In this lecture, you will begin realizing that there are two types of cellular reproduction. One type will reproduce a cell identical to the parent cell. For instance, a skin cell will reproduce another skin cell. The other reproduction preoduce offspring in which a whole individual is created, not just a single cell.
I lecture one we will concentrate on concepts common to both and focus on concept specific to the first type of reproduction, mitosis. We will learn about genes and chromosomes. and more about DNA. You will get to meet an interesting family of siblings as we begin learning about the phases of cellular reproduction. Older brother Pro Phase, sister Meta Phase, little Anna Phase, and baby Telo phase. This fun way to learn the phases will help the details that occur in each phase of cellular reproduction stick in your memory.

L2 Meiosis: Sexual Reproduction; Viruses
Lecture 2 gets a little more technical but the foundations that are laid in the first lecture, particularly the phases will be built upon as the more complex type of cellular reproduction occurs that lead to an offspring with a new genetic mix.
Lab: Extract Onion DNA
DNA is relatively easy to extract form any cell. A classic lab is to extract onion DNA. In the slideshow, you can follow Zachary as he does this lab. You will need an onion, rubbing alcohol, a pan for heating the water on a stove, and a tall and narrow clear glass. The captions will walk you through the steps.
Lab: Phase ID and percentage Time in each Phase
In this lab you will be looking closely at cells and by sight identifying what phase of cellular reproduction they are in. You will then calculate the percentage to deteremin what phases the cells stay in the shortest to longest period of time. You will need close attention ti visual details for this one. WHile you could do this lab using your microscope, I actually recommend using the image provided in the lab report starter so that the cells can be seen better.
CSI Web Adventure
The rest of lab day will be used to explore how CSI investigators use cellular information as well as other clues to solve crimes. The link is http://forensics.rice.edu/index.html
