Sarah Brantner: Lab Project 1: Building a cell

This project has helped me out in understanding cells and how they go through mitosis, replication, and translation. This lab was completely hands on! Constructing the cell structure was the easiest part of this lab. Trying to figure out how to represent DNA replication, translation, and mitosis was a difficult task. When trying to show mitosis and the translation of DNA helped me understand the process a little easier and gave me more understanding.

While working on this project, here are the items that I used....

Cell plasma: Black licorice

Nucleus: Purple Frosting

Nucleolus: Rice Cake

Nuclear Membrane: Red Licorice

Rough ER: Walnuts

Smooth ER: Blue M&M's

Golgi Aparatus: Twizzlers Pull and Peels

Lysosomes: Yellow Peanut M&M's

Vesicles: Orange Peanut M&M's

Mitchodria: Raspberries

Cilia: Pink Fish Sprinkles

Chromosomes: Black and Red licorice

DNA: Red and Green Sour Candy Strings

Base for DNA: White, Gray, Black, and Blue Fish Sprinkles

Ribosome: Pink Sprinkles

Polypeptides: Turtles

This is the first picture after the cell structure was constructed. This was quite a messy process as my almost 2 year old decided that he likes just about everything in this cell structure :) I used the book model as a reference for all the cell structures.

Here is a picture of the nucleus and chromosomes waiting to get duplicated. The homologous chromosomes come together and line up next to each other, before they come together to form a sister chromatides.

This is a picture representing the sister chromotides. This is part of Mitosis II. They are joined in the center called centromere.

This was the best way that I could represent the nucleus dividing. As you can see, the chromosomes go to the opposite poles when the nucleous divides.
