Cell Cycle Station Lab - #1

The cell holds an organism’s genetic information in the sequence of nucleotides, or nitrogen bases, found in that organisms DNA. When it is time for cells to reproduce that DNA becomes tightly coiled into the structure shown below. Identify, draw, and label the structure. Where would you find this structure in the cell?

Cell Cycle Station Lab - #2

All non-sex cells in an organism are said to be diploid. This means that they have a full set of chromosomes. After going through the cell cycle, how many chromosomes would be in one daughter cell of a potato?

Cell Cycle Station Lab - #3

Describe what happens in the 3 stages of Interphase. What is the purpose of interphase?

Cell Cycle Station Lab - #4

In what phase of mitosis is the cell below? Describe what is happening.

Cell Cycle Station Lab - #5

How can you differentiate between telophase and cytokinesis?

Cell Cycle Station Lab - #6

In the image below, most cells are in what stage of the cell cycle? Why do you think that is?

Can you identify any of the phases of mitosis in this image? Which ones?

Cell Cycle Station Lab - #7

If all cells contain the exact same DNA, how do cells differentiate and only do a specific “job?”

(Use page 256 in the book and your notes to help you answer this question.)

Cell Cycle Station Lab - #8

For each of the following groups of words, tell which word includes all of the others (umbrella term).

a) Breakfast, lunch, dinner, mealb) Football, sports, volleyball, cleatsc) Chromosome, mitosis, cell cycle, cytokinesisd) Organelle, nucleus, mitochondria, centriole

Cell Cycle Station Lab - #9

Count the number of cells in prophase.

Count the number of cells in metaphase.

Count the number of cells in anaphase.

Count the number of cells in telophase.

Cell Cycle Station Lab - #10

When cells do not respond to signals or checkpoints during cell division cancer cells can develop. What are some effects that cancer cell growth can have on the body?

Cell Cycle Station Lab - #11

Karyotypes are one of many ways scientists and doctors analyze an organism’s chromosomes, genes, and traits. Karyotypes can identify gender and possible diseases and disorders.

Identify each of the karyotypes as male or female and normal or abnormal.

Cell Cycle Station Lab - #13

Describe what is happening in the phase of mitosis pictured below.

Cell Cycle Station Lab - #14

Identify each of the karyotypes as male or female and normal or abnormal.

Cell Cycle Station Lab - #15

Scientists have completely mapped the human genome. Chromosome painting, karyotyping, and DNA fingerprinting are just a few of the tools used to analyze DNA, chromosomes, and the entire genome.

Why would scientist and doctors want to study and compare these things?

Can you think of any real world jobs that would use these tools?

Cell Cycle Station Lab - #16

What are three major differences between prokaryotic cells and eukaryotic cells?

Cell Cycle Station Lab - #17

Why do cancer cells spread so much more quickly than normal, healthy cells?
